I could watch Western Kingbirds all day, they are so graceful in flight. Around here the scissortail flycatchers get back first, many of which are aggressively displaced when the western kingbirds arrive a couple of weeks later.
OTOH western kingbirds depart in August on account of they do their post-breeding molt on the winter range in Mexico/Central America.
Scissortail flycatchers are cricket and grasshopper specialists, catching a lot of their prey on the ground, such prey generally being most abundant late summer and fall. So scissortails hang around on the breeding grounds to molt after breeding. Around here where I am you can find then until November.
‘Nother point of trivia, in Oklahoma scissortails get shotgunned in some places on account of the Indians use their tail feathers for peyote fans.
