### GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
### Preamble
The licenses for most software are designed to take away your freedom
to share and change it. By contrast, the GNU General Public License is
intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on,
we want its recipients to know that what they have is not the
original, so that any problems introduced by others will not reflect
on the original authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at
all.
The precise terms and conditions for copying, distribution and
modification follow.
### TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
**0.** This License applies to any program or other work which
contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work
based on the Program" means either the Program or any derivative work
under copyright law: that is to say, a work containing the Program or
a portion of it, either verbatim or with modifications and/or
translated into another language. (Hereinafter, translation is
included without limitation in the term "modification".) Each licensee
is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the Program
(independent of having been made by running the Program). Whether that
is true depends on what the Program does.
**1.** You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a
fee.
**2.** You may modify your copy or copies of the Program or any
portion of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
**a)** You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
**b)** You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any part
thereof, to be licensed as a whole at no charge to all third parties
under the terms of this License.
**c)** If the modified program normally reads commands interactively
when run, you must cause it, when started running for such interactive
use in the most ordinary way, to print or display an announcement
including an appropriate copyright notice and a notice that there is
no warranty (or else, saying that you provide a warranty) and that
users may redistribute the program under these conditions, and telling
the user how to view a copy of this License. (Exception: if the
Program itself is interactive but does not normally print such an
announcement, your work based on the Program is not required to print
an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
**3.** You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
**a)** Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections 1
and 2 above on a medium customarily used for software interchange; or,
**b)** Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your cost of
physically performing source distribution, a complete machine-readable
copy of the corresponding source code, to be distributed under the
terms of Sections 1 and 2 above on a medium customarily used for
software interchange; or,
**c)** Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is allowed
only for noncommercial distribution and only if you received the
program in object code or executable form with such an offer, in
accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
**4.** You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt otherwise
to copy, modify, sublicense or distribute the Program is void, and
will automatically terminate your rights under this License. However,
parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such
parties remain in full compliance.
**5.** You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
**6.** Each time you redistribute the Program (or any work based on
the Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
**7.** If, as a consequence of a court judgment or allegation of
patent infringement or for any other reason (not limited to patent
issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this License.
If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations,
then as a consequence you may not distribute the Program at all. For
example, if a patent license would not permit royalty-free
redistribution of the Program by all those who receive copies directly
or indirectly through you, then the only way you could satisfy both it
and this License would be to refrain entirely from distribution of the
Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
**8.** If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
**9.** The Free Software Foundation may publish revised and/or new
versions of the General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Program does not specify a
version number of this License, you may choose any version ever
published by the Free Software Foundation.
**10.** If you wish to incorporate parts of the Program into other
free programs whose distribution conditions are different, write to
the author to ask for permission. For software which is copyrighted by
the Free Software Foundation, write to the Free Software Foundation;
we sometimes make exceptions for this. Our decision will be guided by
the two goals of preserving the free status of all derivatives of our
free software and of promoting the sharing and reuse of software
generally.
**NO WARRANTY**
**11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
**12.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
### END OF TERMS AND CONDITIONS
### How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
one line to give the program's name and an idea of what it does.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

appropriate parts of the General Public License. Of course, the
commands you use may be called something other than \`show w' and
\`show c'; they could even be mouse-clicks or menu items--whatever
suits your program.
You should also get your employer (if you work as a programmer) or
your school, if any, to sign a "copyright disclaimer" for the program,
if necessary. Here is a sample; alter the names:

Natuurlijke_variaties_in_het_gedrag_van_de_wildrobin_onthullen_fascinerende_patr – Baywoodproperties
Natuurlijke variaties in het gedrag van de wildrobin onthullen fascinerende patronen en aanpassingen
De wildrobin, een geliefde vogel in de Nederlandse tuinen en natuurgebieden, staat bekend om zijn melodieuze zang en opvallende verschijning. Dit kleine, maar krachtige vogeltje vertoont een fascinerend gedrag dat voortdurend aanpassing en variatie laat zien, afhankelijk van de omgeving, het seizoen en de individuele omstandigheden. Het bestuderen van deze variaties biedt inzicht in de complexe relatie tussen dier en habitat, en de veerkracht van de soort in een veranderende wereld.
Het gedrag van de wildrobin is niet statisch; het is een dynamisch proces dat voortdurend wordt beïnvloed door externe factoren. Zo kan de zang veranderen in intensiteit en frequentie afhankelijk van de aanwezigheid van rivalen of potentiële partners. Ook de foerageerstrategieën variëren, waarbij de vogel zich aanpast aan de beschikbare voedselbronnen. Deze aanpassingen zijn cruciaal voor het overleven en succesvol voortplanten van de soort, en maken de wildrobin tot een boeiend onderwerp van ornithologisch onderzoek.
Voedsel en Foerageergedrag
Het voedsel van de wildrobin is sterk seizoensgebonden. In de lente en zomer voedt hij zich voornamelijk met insecten, wormen en andere ongewervelden, die essentieel zijn voor de groei en ontwikkeling van de jongen. Tijdens de herfst en winter verschuift de focus naar bessen, zaden en vruchten. Deze aanpassing aan de beschikbare voedselbronnen is een belangrijk aspect van het overlevingsstrategie van de wildrobin. Het foerageergedrag varieert ook sterk; soms zoekt de vogel actief naar prooien op de grond, terwijl hij op andere momenten vanuit een strategische positie op bomen of struiken afwacht.
De Invloed van het Weer op de Foerageerstrategie
Het weer speelt een significante rol in het foerageergedrag van de wildrobin. Tijdens regenachtige dagen is het moeilijker om insecten te vinden, waardoor de vogel zich vaker richt op bessen en zaden. In strenge winters, wanneer de grond bevroren is, kan het vinden van voedsel een uitdaging zijn, en kan de vogel afhankelijk worden van voedsel dat door mensen wordt aangeboden. Deze flexibiliteit in foerageerstrategieën draagt bij aan het vermogen van de wildrobin om te overleven in diverse klimaten en omstandigheden. Het vermogen om snel te schakelen tussen verschillende voedselbronnen is een teken van een succesvolle aanpassing aan de omgeving.

De tabel illustreert duidelijk hoe de wildrobin zijn voedsel en foerageerstrategie aanpast aan de verschillende seizoenen en weersomstandigheden. Dit aanpassingsvermogen is essentieel voor het overleven en succesvol voortplanten van de soort.
Zang en Communicatie
De zang van de wildrobin is een van de meest kenmerkende aspecten van dit vogeltje. De melodieuze trillingen dienen niet alleen om partners aan te trekken, maar ook om het territorium af te bakenen en rivalen af te schrikken. Het repertoire van de wildrobin is verrassend uitgebreid, en individuele vogels kunnen variaties in hun zang vertonen. Deze variaties kunnen dienen als een soort ‘handtekening’, waarmee individuen elkaar kunnen herkennen. De zang is ook afhankelijk van de tijd van het jaar en de omgeving. In de vroege lente, wanneer het broedseizoen begint, is de zang het meest intens en frequent.
De Rol van de Zang in de Balts
De zang speelt een cruciale rol in de balts van de wildrobin. Mannetjes zingen om de aandacht van vrouwtjes te trekken en om hun kwaliteit te demonstreren. Vrouwtjes beoordelen de zang van de mannetjes en kiezen de meest indrukwekkende zanger als partner. De complexiteit en variatie van de zang worden vaak geassocieerd met de gezondheid en genetische kwaliteit van het mannetje. Naast de zang maken wildrobins ook gebruik van andere vormen van communicatie, zoals roepen en lichaamstaal, om met elkaar te communiceren. Deze combinatie van zang en andere signalen maakt de communicatie van de wildrobin bijzonder effectief.

Variaties in zang dienen als individuele herkenning.
De complexiteit van de zang weerspiegelt de kwaliteit van het mannetje.
De lijst illustreert de diverse functies van de zang van de wildrobin, die essentieel zijn voor de voortplanting en het territoriaal gedrag van de vogel.
Territoriaal Gedrag en Nestbouw
Wildrobins zijn territoriaal, en verdedigen hun broedgebied fel tegen indringers. Het territorium omvat niet alleen het nest, maar ook de directe omgeving waar de vogel foerageert en zingt. De grootte van het territorium is afhankelijk van de beschikbaarheid van voedsel en de dichtheid van de populatie. Mannetjes verdedigen hun territorium door middel van zang, roepen en agressieve displays. Nestbouw is een belangrijke activiteit in het voorjaar. Het nest wordt meestal gebouwd in struiken, heggen of bomen, en bestaat uit gras, mos, wortels en andere plantaardige materialen. Het nest is zorgvuldig verborgen om te beschermen tegen roofdieren.
Invloed van de Omgeving op de Nestbouw
De omgeving heeft een grote invloed op de nestbouw van de wildrobin. In gebieden met veel bomen en struiken zijn er meer geschikte nestplaatsen beschikbaar. In open gebieden, zoals weilanden, kunnen wildrobins nesten bouwen in dichte begroeiing of in beschutte hoeken van gebouwen. De kwaliteit van de nestbouw is ook belangrijk voor het succes van de broedpoging. Een goed gebouwd nest biedt bescherming tegen de elementen en roofdieren, en zorgt voor een optimale omgeving voor de ontwikkeling van de jongen. De vogel kiest zorgvuldig de materialen voor het nest en besteedt veel tijd aan de constructie.

De stappen beschrijven de belangrijkste aspecten van het territoriaal gedrag en de nestbouw van de wildrobin, die essentieel zijn voor het succesvol voortplanten van de soort.
Migratie en Wintergedrag
Hoewel sommige wildrobins standvogel zijn, migreren veel exemplaren in de herfst naar zuidelijkere streken om de koude winter te overleven. De migratieroute en de overwinteringsgebieden variëren afhankelijk van de populatie. Tijdens de migratie zijn wildrobins afhankelijk van de beschikbaarheid van voedsel en geschikte rustplaatsen. In de overwinteringsgebieden foerageren ze op bessen, zaden en insecten. Het wintergedrag van de wildrobin is aangepast aan de koude omstandigheden. Ze zoeken beschutting in dichte begroeiing en vormen soms gemengde groepen met andere vogelsoorten.
Adaptaties aan Verstedelijking
Wildrobins hebben zich opmerkelijk goed aangepast aan de verstedelijking. Ze nestelen steeds vaker in tuinen, parken en andere groene ruimtes in steden. Deze aanpassing is mogelijk gemaakt door de beschikbaarheid van voedsel, zoals wormen in gazons en bessen in tuinen. Bovendien bieden steden beschutting tegen roofdieren en extreme weersomstandigheden. Het is belangrijk om groen in steden te behouden en te creëren om de leefomgeving van de wildrobin te beschermen.
Nieuwe inzichten in de verspreiding van de wildrobin
Recente onderzoeken, mede dankzij ringonderzoeken en trackingtechnologieën, hebben verrassende details blootgelegd over de verspreiding van de wildrobin. Het blijkt dat individuele vogels vaak grotere afstanden afleggen dan eerder werd gedacht, en dat er een aanzienlijke uitwisseling van genen plaatsvindt tussen verschillende populaties. Dit onderstreept het belang van het beschermen van de gehele migratieroute en het creëren van een netwerk van geschikte leefgebieden. De kennis over de verspreiding is cruciaal voor het ontwikkelen van effectieve conservatiestrategieën. Door de dynamiek van populatiebewegingen beter te begrijpen, kunnen we gerichter maatregelen nemen om de wildrobin te beschermen en te ondersteunen.
