As you scroll from top to bottom on the right column, here's corresponding answers to the most
recent quizzes for which I have not yet provided answers:
1. Identity of warbler photos from top to bottom: Cerulean, N. Parula, Prothonotary, Swainson's, Yellow
2. Fifty-five or 56 warbler species typically annually occur in N. America north of Mexico.
3. Spruce budworm — which experience boom and bust cycles — is an imperative food resource that is often a limiting factor influencing the nesting success of some boreal forest breeding warblers.
4. Late arriving species in spring vary, but often include all three in the quiz: Blackpoll, Connecticut, and Canada.
Got em all right! John
