On my mid-morning walk today (14 Apr 2020) I saw a group of 3 swallows hunting very close to a fallow field of stubble. They were too far away to ascertain color and I did not see obvious forked tails, but had only my eyes and no bins. I did not hear the chittering of Chimney Swifts, but, again, may have been too far to be within earshot. I was favoring Purple Martin at the time, but they are high hunters. Thoughts?
