I often try to write stories that make a connection between the birds you find in a place and the habitat conditions there. Because habitat is something we can create or alter by our forest practices, this illustrates an opportunity for interested landowners to manage their properties to improve woodland habitat conditions for particular birds. While we focus on birds, it is an illustration that applies to all woodland fauna. Animals tend to be quite responsive to habitat conditions.
Birds are fun, abundant and easy to observe by watching and listening, which makes them a good group of animals for landowners to key in on. In fact, lots of what we know about birds, and how they use different places (migratory arrivals and departure, where the feed and nest) has been gained through careful observation.
But capturing and banding birds is another important tool available to researchers that lets them add another layer of information. By capturing birds, we can learn about their general condition (weight, fat reserves) gender and age distribution, that gives insight on things such as general health or their readiness for breeding or migration. And when lucky enough to recapture a banded bird, we learn valuable details about how they have moved and fared in the time between captures. Continue reading
