Four Lakes FP on Sunday 7/10

A single adult Mute Swan was at Four Lakes Forest Preserve on Sunday morning.

Several pairs of Purple Martins are apparently nesting in the Purple Martin nest box located in the middle of the SE pond. The pole which supports the box is leaning at quite an angle, but the martins are using the box anyway. I watched adults catching insects and flying with food to the box, which was concealed from my view by a tree growing on the “island” that used to be in the middle of the pond. Walking to the north brings the box into view.
