International Bird Day

Conserve the living by conserving the dead

To highlight International Bird Day (January 5), we are honouring cavity-nesters, birds that create their nests in natural tree cavities. In Canada, there are more than 50 species of cavity-nesting birds that require cavities to create their nest and reproduce. Fortunately, some species are specialized in creating their own cavities and produce them every year (e.g. woodpeckers), while other species depend on existing cavities (e.g. swallows).

These cavities are mainly found in dead trees that are still standing, which are becoming increasingly rare (cleaning of forests, trees cut down for economic or safety reasons, etc.). In order to reproduce, birds must then compete for access to nesting sites that are scarce, which has led to the decline of several cavity-nesting species.

Did you know that you can contribute to the conservation of these species? Preserve old growth forests and decaying trees! Provide artificial nesting sites, like nest boxes! If you must cut down a dead or diseased tree, cut only the top part and preserve its rooted base!

Join the Granby Zoo and commit to preserving cavity-nesters. The Granby Zoo maintains and monitors over 60 nest boxes in Granby with the help of the Club d'Observateurs d'Oiseaux de la Haute-Yamaska (COOHY). By offering nest boxes as artificial nesting sites, we have aided in the fledging of nearly 450 chicks, since 2017! Our nest boxes are home to 7 species of birds annually (Tree swallow, eastern bluebird, American kestrel, wood duck, black-capped chickadee, house wren and house sparrow).
