The barred owls

Walkies after dinner, I thought. It is supposed to be quite healthy. I was just finishing up dinner and I heard the owl's familiar song: You can listen here: Barred owl when I heard him talking to his mate in the daytime.
'Who-cooks-for-you? Who-cooks-for-you-aaallll?'
I found him on a branch, again. Daisy helped. I'm going to have to ensure she is locked up when I do this again.

I went to my book on owls, Owls of the U.S. and Canada  by Wayne Lynch.

Characteristics

This barred owl was killed on the highway
Their talons can spread 13 - 15 cm, or 5 - 6" wide. Lynch calls them 'Weapons of Mouse Destruction!' You can seem them in these photo from the dead owl we found at the side of the highway.
Dark brown eyes, a pale yellow beak.
"Mainly nocturnal."

Nests

All About Birds
Barred owls either build a nest in a tree, or use a cavity. It has to be a big one, as they are large birds! They prefer a cavity, obviously, and can use a particular tree for 10 years. This is why I'm rather eager to find their nest. The ones who are born in a nest climb onto the branches. That would make them easier to spot.

They fledge in 4 - 5 weeks. In the meantime, using their wings, owlets can climb 6 metres up a tree, using strong talons, before they can truly fly.

This owl has been sitting high atop a gully, with wetland below. A perfect spot from which to survey his territory. He seems rather sleepy in the day (they are nocturnal), thankfully for Daisy. I've scoured the dead trees to no avail. They prefer a hidden, empty cavity, to a tree top nest. I think this pair is in a cavity somewhere.

Since they incubate a month, and nest a month, I thought I might have a chance to figure out where the nest is, but so far, no luck! My birding community suggest I go out at dusk and listen for them as the chicks call for food at this time. I have a better chance now that there aren't any leaves out, but I'm giving up hope!

The male brings her food, and she will feed the chicks once they hatch. The male barred owl might feed the chicks, Lynch says, but he won't dismember it. Momma owl will clean up the nest, eating feathers and feces the chicks leave for her.

Owl chicks in a nest ( as opposed to a cavity) will become branchers, as they move out onto the tree branches, still being fed by parents, howling for food. This is dangerous, and must be a risky period of time for the family. The noise of the chicks can attract predators (e.g., Great horned owls – one nested in the forest across the highway).



Below, I've embedded the Wild Birds Unlimited nestcam!

Food sources

They sit and watch for victims, but they can hunt like hawks do, zooming across a spot and cruising for prey. They estimate, from research, that 2/3s of their prey get away. When they eat a mouse, they swallow it whole. The indigestible bits (fur, bones, etc.) come back out in a pellet. I've been back several times and found a couple more pellets. He seems to sit in the same tree, night after night. These owls can eat 10 mice in a row, if they catch them.

They eat small mammals, birds, amphibians, fish and invertebrates.
This is a feather I've found on his favourite perch. A large tree in a different part of the forest. This is where I've been finding owl pellets. What the heck, the curiosity was killing me. I dissected them and found he'd snagged something relatively large. Thankfully, not Daisy!



 Potential nests are few and far between 

The older dead trees have to be large enough to accommodate the larger owls. I would love to save up for a barred owl nesting box, but they seem to be doing fine! The dead trees are beautiful.

Walkies with Felix in the bog

Hard to believe we had this snow last week!
Yes, off we went. Buster was a bit sleepy. He'd caught a mouse, and we quite exhausted. He was camped out on our bed.

He brought it up to the deck to show off his prize. Duly tenderized, it has since disappeared!

I headed out back to check out the property with Felix. Our backyard is a bit of a spit, extending out into the wetland.

We have no worries about flooding, as the bog is in a gully below, with much clay underneath.

Brave Felix digs snow out from toe pads.
It is much like the larger lakes, and melts at the edges first, where meltwater has gathered.
And still we have people sledding at the speed of stupid!


Nothing more striking than the moss!
Felix hunts for mice friends!

Field mouse trails appear 

They look a bit drunk, wobbly little path!

Much safety in the snow cover!
I shall miss the story that the snow tells.

He's happy with the green grass!

Can you spot them?!

You can see the path the deer follow in the bog.
Where they have compacted snow
it is slower to melt.

He walks with me like a dog!

You can see the melt starting!

He loves getting up off the snowy, wet ground!

House peeks through the forest!

Oops, watch that first step!
And still we had people go into Lake Simcoe!


    Usually letting his brother do the meowing,
    he howled for me to wait up!
    The tree gather sun's rays and warms the forest edge, where snow melts and deer seek warmth.
