Checked out one of the biggest Purple Martin colonies in Austin with the @travisaudubonsociety #purplemartin #birds #birding #atx

A clutch of Purple Martin eggs, then nestlings at one, three and six days old. The adult male martin adds green leaves with which the adults sometimes partially cover their eggs and young. #purplemartins #purplemartin #iroquoisnationalwildliferefuge #purplemartinlandlord

Purple Martin (Progne subis), a female, prepares for a landing at its housing structure. This largest of swallows in the Americas is built like a Formula 1 race car, sleek, lightning fast and capable of tight, high-speed turns; except the bird does all that in three dimensions. Purple Martins are aerial insectivores, snatching flying insects at altitudes up to a km above ground level. They are very good at it. Mathematical modeling studies suggest that the North American population of Purple Martins annually consume about 400 billion insects with a dietary biomass of approximately 115 thousand metric tons (Kelly JF et al., 2013, PLOS one, https://doi.org/10.1371/journal.pone.0076616). Although people might hope that in return for the favor of providing nice nesting boxes for Purple Martins, they could at least include mosquitoes in their diet. However, they apparently don't care much for mosquitoes (Kale HW, 1968, The Auk, 85(4), 654-661). Perhaps the martins think the man-made nesting boxes, on which they are now rather dependent, are hardly adequate compensation for the widespread use of insecticides that decimate their food supply and the systematic removal of deadwood trees that they formerly used for their cavity nests.
