I have seen lots of Black -throated Blue Warblers this fall at Lorimer Park. They seem to love the berries on the Tree of Heaven. The Tree of Heaven is considered a junk tree but it has a pretty pink flower in fall and lots of purple berries. The Black-throated Blue Warblers are drawn to the berries. I have see 10+ almost every time that I have been to Lorimer Park where there is a grove of these trees. I finally got some photos the other evening. Here are the only 2 that really turned out.
