It had been slow times recently for birding in the county. Tim Spahr texted me the other day and had my nemesis bird at Westboro WMA, an Olive-sided Flycatcher. and like the 10 plus times I have tried for one it disappeared. He also had Black-crowned Night Herons there. I also didn't find those after search for over an hour and half. Last night I decided to check Notre Dame Cemetery in Worcester for night herons. The foliage is very thick and through one crack I noticed white in a dark backround of leaves....I backed up the car and got on it.. Black-crowned Night Heron it was! I was getting worried about finding one this year as I missed them in the spring.
