APR. 25, 2010 - NOVA SCOTIA BIRD SOCIETY/BLOMIDON NATURALISTS SOCIETY  
FIELD TRIP for birds of eastern King's County, led by myself.

Our day started out not so good, with early morning showers.  But the  
field trip stayed dry, with the day gradually brightening and then in  
mid-afternoon becoming Sunny and clear and fairly warm (16 C.).

(Participants included Helen Archibald, Luke Berrigan from Acadia  
Univ. Biology, David and ?? Burton from Wolfville, Patricia Chalmers,  
Guan ?? from China, ?? Jordan from west of Gaspereau, Patrick Kelly  
from Falmouth, Chris Pepper from Halifax?, Clarence Stevens Sr. &  
Clarence Stevens Jr. of Halifax, plus Liz Doull and several  
neighbours and relatives of Bernard Forsythe just for the "owl show".)

We had about 25 people for the first part at the home of Bernard  
Forsythe on Wolfville Ridge.  Bernard thinks the female barred owl of  
his back-yard pair is a relatively new replacement for a road-killed  
owl about three years ago.  For the past two years this pair laid no  
eggs, but this year they have produced two, the first of which came  
on March 24.

First we located the perched male of this pair, in a tall spruce  
right next to the trunk, and everyone got good looks at him.  Then  
Bernard put on his crash-helmet and used a ladder to get up to the  
nest-box.  He tapped gently on the box, and the female emerged,  
paused very briefly in the entrance-hole, then flew off a short  
distance and perched in a deciduous tree.   One woman who was with us  
got some very nice photos of the female leaving the box.  And this  
year the female owl did not attack Bernard (this time).

Bernard reached into the box and pulled out a very tiny hatchling  
barred owl that was covered in whitish down.  He held it up for us to  
see with binoculars.  He said the hatchling was only one day old, so  
that makes the incubation period for that first egg about 31 days.

He also said that prey items in the nest-box were two meadow voles  
and a song sparrow.  And later he told us about how opportunistic  
barred owls are in their dietary choices (which vary from small  
snowshoe hares and other smaller mammals through various birds,  
salamanders and frogs, various fishes, to beetles, earthworms, etc.

Bernard had a road-killed red squirrel as a food offering for the  
owls, but this time they did not take it from his feeding platform.   
They are used to being fed in the evening, from winter to when the  
baby owls get fledged in mid-summer.

We heard the owls calling a bit when we left the back yard, plus a  
crow that was undoubtedly harassing the male?

Bernard told us the story of one of his nest-boxes being very old and  
having rotted to the point that it fell to the ground.  That same day  
Bernard checked it and found a single unbroken egg plus several  
barred owl feathers, so he thinks the owl was in the box with the egg  
when it fell.  He saved the egg, then went home and built a new box,  
and put it up where the old one fell.  A later check revealed two  
more eggs plus the one he saved, and incubation continues there.

In Bernard's yard someone heard or saw a purple finch, and there were  
also bright goldfinches, chickadees, mourning doves, etc.

(rest of report will be sent separately, because rather long -- sorry)

Cheers from Jim in Wolfville
