appended a notice I sent to our NatureList a few days ago, and last
night, when we had the first resumed calling heard from our house, it
was just a few cold Toads, with no Peepers. It seems to me that Peepers,
being so small, are reluctant to cross dry areas from their hibernation
sites to the breeding ponds unless the ground is wet from rain, and then
when there's rain they may all come down at once and do a lot of
breeding in a single night - and amplexed males don't call. The
intensity of calling is easy to assess, but it may not be a good measure
of frog populations for spring-breeding species, since the breeding
seasons where everything gets done in a couple of nights are likely the
best for the frogs, through reduced predation and exhaustion.

Subject: [NatureList] Frogs & Toads not calling in a frigid April

Everyone,
In 2002, 2005, 2008, 2010, and 2012 we'd already heard Treefrogs calling
before today's date. This year we'd already heard Toads from home (along
with Peepers and Wood Frogs) on 12 April, but then things closed down,
and except for Peepers on the 13th, we haven't heard any Anurans from
home since. Wood Frogs had mostly gotten done with breeding before
things cooled down, and Chorus Frogs have apparently bred during the
days, but it's going to be very interesting to see what's going on and
calling when spring resumes. We saw, for example, a few Leopard Frogs
crossing roads from creeks when it was warm, but it's going to be very
interesting to see if this migration resumes with warmth. - fred.
