The 1994-2003 surveys of the North American Breeding Bird show the summer dispersal and abundance of Canada goose. Through the extensive interest in birds, lots of people have been working on the projects for collaborative ornithology, covering large geographic scales. These resident science projects involve countrywide projects such as the Backyard Bird Count, the North American Breeding Bird Survey, Christmas Bird Count, the Canadian EPOQ, or regional projects like the Asian Waterfowl Census. The projects help classify the distribution of birds, arrival and departure dates of relocation, their population mass and transformations over time, breeding period, and even population heredity. The results of several of these projects are issued as bird atlases. Migration studies by colour marking or bird ringing often include the cooperation of citizens and associations in different countries.
The European Union for Bird Ringing (EURING) supports the research needed for the scientific understanding and conservation of wild birds. Constant Effort Sites Ringing (CES) intends to monitor the abundant development, survival, and productivity of birds all over Europe. They can examine the demographic mechanisms accountable for population changes by studying survival and productivity. Volunteer ringers have taken charge of CES plans in some 11 countries all over Europe.
EURING is managing to organise the significant monitoring efforts and is developing strategies to encourage standardisation between countries. It also desires to promote more examination of data and accepts applications in analysing particular data sets. EURING has created a position report on Avian Influenza which suggests the causes as to why constant bird ringing is fundamental and details the hygiene protections needed to ensure that it can be made safely.
