Northern Goshawk: I spotted a juvie bird circling on a hot sunny day. Russ Jones had it the next day chase a green heron out of a woodlot!
Common Raven: Regular back home, but very uncommon in Essex County. Yesterday, one flew over my study site calling while being harassed by crows.
Acadian Flycatcher: One was present for a few days in the Spring-garden area. I found it on May 10 and it was seen that evening by Jon Pleizier, Shane Butnari, and Russ Jones. Seen on the 11th as well.
Kentucky Warbler: On May 11, I was present in a field while a group of planters where relocating native tallgrass species. I saw a few warblers in some nearby poplars. A bit of pishing produced a gorgeous Kentucky warbler, which approached to within 10 feet of me.
Connecticut Warbler: One male heard and seen at close range in the Spring-garden area.
Cerulean Warbler: Two singing males!
And of course, Eastern Foxsnakes:
