The dead screech owl lay beneath a conifer
in the yard; but it hadn’t been dead long. It was in full rigor mortis which, in an animal this size and depending on
temperature, usually
begins an hour or less after death and lasts
less than 24 hours. The bird appeared to have a broken right wing which drooped
somewhat loosely.
Rather than burying the bird, I decided to set
a camera trap to capture photos of the scavengers that came for a meal. During
the first 24 hours the camera was in place, nothing fed on the carcass. The
next night an opossum visited and a series of photographs showed that it ate
part of the owl.
The next night a gray fox arrived –
And the fox marked the spot as its own –
The fox visited repeatedly over the next
week, eating some of the screech owl on numerous occasions.
At about the same time a wandering house
cat stopped by; but there was only a single photograph of it so it apparently
didn’t stay long.
Other visitors to the remains were an
eastern chipmunk, which came on the eighth day –
And a gray squirrel, or squirrels, that
visited repeatedly –
Rodents like the chipmunk and squirrel regularly
gnaw on bones for the calcium they contain. What many people don’t realize is
that these rodents also eat meat and frequently kill and eat nestling birds and
smaller mammals.
The last visitor before the camera was
removed was a gray fox that came on the 17th day –
By that time, the only discernible remains of
the screech owl were several of the long primary wing feathers. The fox must have been attracted by the residual scent because there was nothing left to eat.
Interesting experiment. I really should look into a trailcam, just for fun.
ReplyDeleteNothing goes to waste in nature. I just got a trail camera to check out what's happening around our cabin home. - Margy
ReplyDeleteHello, interesting experiment. Your camera showed many critters coming to fed on the carcass. The fox is beautiful. Great post and photos. Thank you for linking up and sharing your post. Have a great day!
ReplyDeleteNice work with that camera trap, several of those shots are very good.
