Owl Research

Results from the early years.



Results for 2002

The slump in the owl populations appears to be continuing. There are now 38 nest boxes available, and of these, three had squirrel nests (two reds, one unidentified), one had an American Kestrel and one in Jim Campbells Barrens had a Northern Saw-whet Owl. Two more boxes have been put up, with another 10 left to go.
 

This nest had 5 eggs, 06 June 2002 We didn't need the pole-top camera for this bird (camera held by Don). Putting up yet another box.

Thanks to Barry, Sean, Jody and Don for the companionship, help and tolerance to the rain!


Autumn 2002


On October 4th, Erin, Steve and Sean accompanied me to the Cape Breton Highlands National Park where we put up the LAST SIX NEST BOXES!!!! This is the fourth year of putting up nest boxes, originally built with grant money from Stora Enso (Port Hawkesbury). Here are a few pics.

Results for 2001

Twenty-seven nest boxes were available for owls this spring; one was stolen, one was shot. One box had a Red Squirrel nest, two others had unidentified squirrel nests. The winter was a tough one, way too much snow cover (rodents loved it though) so the owls had trouble finding prey. Dead Saw-whets were turning up around the province. One nest boxer on the mainland reports his second lowest number of nests ever (two - only beating 2000 when only one nest was found). Even squirrels seemed low in my boxes this year. I'll be putting up more boxes before the next breeding season starts.
 
 

Rats, another empty nest. Mike checking last year's successful box.



Results for the year 2000

In several of my nest boxes, Flying Squirrels have nested. I presume they are Northerns, Glaucomys sabrinus. By the way, these nest boxes were built by my nephews, Nicholas and Bradley Elliott - Thanks Guys!

However, of the 23 nest boxes in suitable Boreal Owl habitat, one box this year hosted Northern Saw-whet Owls Aegolius acadicus. More boxes will be put up next spring when I to to check the current ones; more will also be put up at various times next summer. I'll need volunteers for those trips. Drop me a note if you're interested.
