A nestling is a young, recently hatched bird that has not yet grown any flight feathers and is unable to fly. Nestling birds are entirely dependent on their parents for food and protection. The length of that dependency varies for each bird species from just a few days to several weeks. Baby birds have very demanding dietary needs. Depending on their age and species, they eat every 10-20 minutes for 12-14 hours per day.

CHIMNEY SWIFT ($25 Monthly)
A chimney swift is a small to medium-sized, swallow-like bird with mainly dark gray plumage and long narrow wings. Also known as a chimney swallow, they often build nests inside an unused chimney. The chimney swift is a beneficial bird that consumes mostly flying insects, including various species of flies and mosquitoes. Researchers estimate that a pair of adults provisioning a nest with 3 youngsters consume the weight equivalent of 5000–6000 housefly-sized insects per day.

GREAT BLUE HERON ($50 Monthly)
The Great Blue Heron is a large wading bird in the heron family, common near the shores of open water and in wetlands over most of North America. Typically, the Great Blue Heron feeds in shallow waters, usually less than 20 inches deep, or at the water’s edge during both the night and the day, but especially around dawn and dusk. A rehabilitating heron will consume as much as 6 dozen live minnows and goldfish a day as well as dead smelt and sardines.
