Hi Andrew & All, Aug 3, 2013
Good to her about this much bat activity.=20
In the yard I have observed only one burst of fair activity (16 =
passes over the back lawn in five minutes; likely one bat only: =
9:20-9:25 pm, July 28, overcast & calm).=20
Does the Batbox (all news to me) just convert high frequency sounds =
to an audible (to humans) range or does it do more ? Does it reduce the =
frequency of all sounds or just vHF ?
With regard to the height and depth of that band of mosquitos, how =
do you measure this ? With a very tall scout or something more =
sophisticated ?
Bats patrolling pavement early in the evening reminded me of the =
clouds of Mayflies that follow a canoe on calm evenings and the similar =
clouds that collect over a stationary wharf. Why fight gravity if you =
can glide on an updraft ?
Yt, Dave Webster, Kentville

Subject: [NatureNS] Bats Friday 2 Aug
I took a small scout group fort a bat walk from Lawrence House to =
Maitland (along the dykeland) and then to Oak Island cemetery (Hants =
East).. Temp of 21C, no wind, partly cloudy
Using Batbox IIIs we encountered bats at 4 sites - (1-2 at each =
site). This is more activity than we had seen 6 weeks earlier at the =
same site .. usually a good site to see them.
At the Lawrence House parking lot, there was a band of mosquitos - =
about 30 cm in depth at a height of about 2 m when we started. they =
were gone by the time we returned (1 1/2 hrs)./
While returning to the farm (14 km west of there), we observed 22 bats =
in the stretch from Selma to Stirling Brook - probably little brown =
bats, flying along the pavement at about 3-5 m height.. typical early =
evening patroling style.
I was not expecting to see as many, since our previous 2 walks =
(Maitland and Smileys Park) produced very poor results.
Andrew
