Hi Laura and all, I agree that those are all Cape May Warblers.
In a post to this forum earlier this year, I noted a dramatic increase in Cape May Warblers and Bay-breasted Warblers during the autumn of 2015 in Nova Scotia. In years previous, these species have been scarce both in acoustic recordings and in the field. These species are known as spruce budworm dependent species and I speculated in that previous post that perhaps this increase is related to the current spruce budworm outbreak in the eastern boreal forest. This year, Cape May Warblers first started appearing in numbers in my recordings this week (the last week of August). Birders in Nova Scotia have also been reporting them regularly on regional list serves and Facebook. I have also seen more Tennessee Warblers this month than I have for a number of years; not as dramatic an increase as Cape May Warbler but notable. It is a third spruce budworm dependent species. Regional media are reporting flights of spruce budworm being seen on weather radar in northern New Brunswick and Quebec. The Nova Scotia government is now considering a control program using a BTK (bacterial) or Mimic (hormonal mimic) spray. I don’t know if other jurisdictions have started or are considering control programs. I would think that control programs, if extensive enough, would negatively impact the budworm dependent warblers and perhaps other warbler species from the kill of non-target insects. Perhaps there are some boreal forest specialists on this list serve who could shed more light on this matter.

I get a significant number of the calls illustrated in this clip from the night of 29-30 August, 2016, and the Cleveland Lakefront Nature Preserve (about 0.3 km from the south shore of Lake Erie, east side of Cleveland). The only thing that seems to match is Cape May Warbler, but we see only a handful of Cape Mays here. Does anyone have a suggestion for a different ID? Am I missing something obvious? If not, do others also see a disproportionate number of Cape May calls?
