Make sure you know when the baby birds are due to fledged. This occurs at different times depending on the species; for example, bluebirds fledged at days 16-21, tree swallows at days 18-17 and purple martins at around 20 days. Open nesters generally fledged around day 12, while cavity nesters stay longer.
1 TREE SWALLOW: The Tree Swallow is a common swallow of marshes and open fields. 2  It is an inhabitant of nest boxes. 3  The Tree Swallow winters farther north than any other American swallow, and it returns to its nesting grounds long before other swallows come back. Cliff Swallow chicks only get to leave the nest once, no going back. 2  They have to wait until the time is right. 3  An unmated male Barn Swallow may kill the nestlings of a nesting pair. 4  His actions often succeed in breaking up the pair and afford him the opportunity to mate with the female.
