The chorus of calls has clearly changed over the last few weeks;
interesting to monitor the dropping out of calls as the season progresses.
Beavers have dammed a feeder stream that flows into Lake Memphremagog. The
resulting flooded area has created a new, rich habitat that birds and frogs
have taken advantage of-bitterns, green herons, and sora and Virginia rails
have been species of note. Also a new bird for me, marsh wren, has really
moved-in in surprisingly large numbers. Today I observed one calling and
collecting mouth-fulls of cattail head material then flying off to a
nesting site. House wrens, robins, phoebes, common yellow throat, alder
flycatcher, and goldfinches remain in full song. The chestnut-sided
warblers that were so prominent have gone quiet.
