About this survey
Aggression between different species is
perhaps the most striking bird behaviour observed by people in the places where
birds and people coexist. Certain
species have reputations as "Bully Birds" and they are commonly
believed to limit the occupation of gardens and other areas by more
The aim of this survey is to systematically
record aggressive interactions between bird species to determine the relative
importance of different aggressor species, and the degree to which they may
structure backyard bird communities
Take part in this survey
survey involves recording acts of bird aggression that you might observe while
conducting the 20-min Backyard Bird
Survey and is a supplement to this survey.
During your survey you will need to note any aggressive interactions you
observe during your 20-min survey, and record the species involved attacks and
responses, location and resource being disputed.
The ‘Birds in Backyards' Program have
established a new survey called "Backyard Biffo". The form is very easy to fill out and any
observations you can make would be a great help. Please try and contribute to this survey
which is located at http://www.birdsinbackyards.net/surveys/backyard-biffo.cfm.
