Second Clutches Underway for PROWs at Northwest River


By Shirley Devan, Volunteer, Coastal Virginia Wildlife Observatory

We are checking the Prothonotary Warbler nest boxes every week down in Chesapeake at Northwest River Park. These days we're finding lots of second clutches.

But sometimes we find other wildlife…like a Black Rat Snake in one box a couple of weeks ago. Now that's a surprise. Unfortunately, the snake had eaten PROW nestlings. Subsequently we repositioned that box.

The PROW nestlings are only in the box for 10 days before they fledge. Steve Living and I have a short window to band nestlings, who should be 5 grams or 5 days old when banded.

We've banded over 100 nestlings so far and trapped over 30 females, four of which were banded as adults in 2009! At least four migratory round trips for these ladies.
