Not quite home: Nests and Avian Architecture

Woven nests: Village Weavers (Rwanda)


Birds are consumers in their environments beyond food; they use space, plant material, mud, spider silk, mammal hair, rocks, and other materials to construct their nests. In some cases birds construct other structures, like bowers or food stores.

According to Avian Architecture, by Peter Goodfellow, the vast majority of birds do not live in their nest, although there are exceptions. The primary function of the nest is to contain eggs for protection and incubation, and then for many species, for raising the young until they can fledge (defined by the book as growing feathers and being able to fly). For many other species, the young are born from the egg with feathers and without a need for parental care. Nests are then often abandoned or perhaps reclaimed the following breeding season.

A migrant’s hello from Ecuador

Summer Tanager (Piranga rubra)
near Santa Lucia Bosque Nublado, Ecuador

My favorite time of year in New York was always the first two weeks of May. Early mornings before work, afternoons after work, and pretty much every minute of the weekends were spent combing Central Park for migratory birds that were passing through on their way to their breeding grounds.
