This is especially true when they are flying close to the ground or in among the trees or in a place where they have to steer carefully but to my notion they do so more especially when there is no breeze to buoy them up. I have watched these birds when attacked by Brewer's Black birds and have discovered that they are more agile in flight than the Red Tail or other larger hawks in their efforts to get rid of their tormentors by dodging. I noticed that the Parkman's Wren stayed and cared for her brood a long time after they left their nest. This nest was in an old Cliff Swallows nest in the barn which had been used only a short time before by a pair of House Finch at a nesting place
