>The Gaint Ragweed (a hay-fever sufferer's nightmare, a >Connecticut Warbler's dream habitat) Gail, Thanks for the interesting post on habitat and for explaining why I've been sneezing so much lately. I'd like to add to the habitat discussion. The Mourning Warblers I saw in the spring were in much different habitat than the Oporornis Warblers I have seen this fall. All four of them were in thickets close to the creek that runs through the park. I don't know if there is something special about the east side of the creek, but that's where they all were (except one of them briefly investigated the opposite side of the creek). One of the thickets that hosted a Mourning Warbler had a Kentucky Warbler a few days later. These birds definitely seem to be picky about something. Based on what I have seen, the fall birds seem to prefer open areas along forest edges. The habitat at Wakefield also seems to be attractive to other genuses. For example, I noticed that several warblers staked out temporary territories this spring for periods exceeding a week, including a Northern Waterthush, a Chestnut-sided Warbler, and a Blue-winged Warbler.
