Hawks attack jays which just don't care

Call it a case of unintended consequences. I had been feeding the birds all summer and had attracted large groups of blue jays and gold finches especially when a few days ago a couple of Sharpshinned hawks showed up. They started attacking the bluejays which, to my amazement, barely seem to care.
Now there are four or more hawks joining in the hunt. They dive bomb the feeder and obviously want the bluejays to fly. Some always do and the nimble hawks pursue them right through the limbs of the trees nearby. Other jays just refuse to take wing.
The jays will return to the birdfeeder immediately after each attack which come every five or six seconds from one or more of the hawks. Incredibly the bluejays will land in the feeder even when the hawks are perched on limbs only 10-15 feet away.
All the little birds such as goldfinches, purple finches, nuthatches and chickadees have vanished.
To my amazement, however, a group of ruffed grouse pecked away in the yard with the air war taking place nearly over their heads.
Go figure!
I have now suspended the feeding operation until the hawks move on.

Rare glimpse of a camera-shy critter

My first photo of a fisher. I have only seen one other

I have had at least one trail camera set up in the bush behind our home here in Nolalu for the past 15 or so years. Sometimes I have had three cameras on the go. I love getting wildlife photographs and it is a hoot checking out my camera cards every day.
I also had an ulterior motive: it seems everyone in the townships south and west of Thunder Bay has seen a cougar, except for me. The Ministry of Natural Resources and Forestry maintains there are no cougars in these parts. They point to a lack of physical evidence -- no photos, no scat, no dead animals -- just eye-witness accounts. As police officers will tell you anywhere, eye witnesses often see what they want to see. Well, I was determined to prove the authorities wrong by getting trail camera photos of the elusive felines.
Now, 15 years later (it might actually be 20) here are my results. I have about 10,000 photos of whitetail deer of which 95 per cent are does and fawns. The next-most photographed animals are timber wolves at a few hundred photos. I have a few dozen photos of red foxes and a few of marten, porcupines and skunks. I have one trail camera photo of a lynx (although I have many more taken with a standard camera through the window of the house.)
Today I got my first photo of a fisher. I saw one other from the house a few years ago.
I have zero photos of cougars.
Do cougars exist here? Well, I have to admit there just is no physical evidence, at least on our land which is crawling with the cougars' favourite food -- deer.
But then, it took me all this time to get the fisher photo and they are known to be common in this area. Also I have no moose photos either and yet tracks tell me they still cross the land here at least once a year.
