What is causing bird population declines? 1. Failure to produce young 2. Failure to survive Rufous Hummingbird
Failure to produce young The number of young produced contributes directly to the size and viability of a population. Habitat loss and predation on nesting grounds can cause nest failures. Song Sparrow with nestlings
Failure to Survive Birds face threats to survival on breeding grounds, wintering grounds, and during migration. Habitat is key to bird survival. We can learn about survivorship by monitoring birds using mist-nets. Northern Pigmy Owl
