this is a breeding pair, so they should be the same. the underside shot on #4 just didnt show the color variation. i have a 5 mp dig cam with 12x and that was the best it would do from the distance. it is strange how much size dif there is in the pair.

bumping this down

The pale underwing coverts and dark flight feathers occur with both Osprey and Swainson's Hawk. Either is possible in this case, but I agree this bird looks better for an Osprey with the dark at the bend of the wing and the style of tail/flight feather banding.

I know that as far as birds go, Swainson's hawks can have trouble finding nesting sites since by the time they arrive from Argentina in the spring, most spots are taken by red tails and such. They often are forced to nest on less desirable spots like power poles which can be very dangerous and also puts them at risk for being destroyed as a "nuisance" or a "hazard." Bees though, I am a little surprised. Many of our native bees, including bumble bees, arw ground nesting, and the rest typically utilize small cavities. Neither would be affected by nesting birds that I could imagine.
