Hi David Webster



Regarding the Batbox... Yes.. that is precisely what it does... In addition=
, you can set the frequency so can ture to frequencies that are used prefer=
entially by different species.  Not as sophisticated as an ANABAT, but good=
 field tool.



Regarding the mosquitos. ... one of the scouts pointed them out..  The bott=
om of the band was just at the top of a newly installed sign (2 m height), =
and just under 1/3 the height of the placard )... very convenient tool.  (T=
here was one boyscout who was not much shorter than the sign as well  :o)

Hi Andrew & All,                        Aug 3, 2013
    Good to her about this much bat activity.

    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).

    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 freque=
ncy of all sounds or just vHF ?

    With regard to the height and depth of that band of mosquitos, how do y=
ou 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 th=
at collect over a stationary wharf. Why fight gravity if you can glide on a=
n updraft ?

Yt, Dave Webster, Kentville

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 o=
f 21C, no wind, partly cloudy

Using Batbox IIIs we encountered  bats at 4 sites - (1-2 at each site).  Th=
is is more activity than we had seen 6 weeks earlier at the same site .. us=
ually 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 t=
he time we returned (1 1/2 hrs)./

While returning to the farm (14 km west of there), we observed 22 bats in t=
he stretch from Selma to Stirling Brook - probably little brown bats, flyin=
g along the pavement at about 3-5 m height.. typical early evening patrolin=
g style.



I was not expecting to see as many, since our previous 2 walks (Maitland an=
d Smileys Park) produced very poor results.
