CSI Door County

Under ordinary circumstances our yard is a busy location if you enjoy bird watching. Five different feeders attracting juncos, finches, nuthatches, jays, cardinals, chickadees and every variety of year round woodpecker known to these parts. 
 
Anyway, before I took doggo out for a romp it occurred to me that the yard had gone vacant and silent. 
 
Not a bird in the neighborhood. 
 
Once we were outside and inspected the snow in the yard there was this.
 
Forensic evidence….

Neighborhood Baldy

A few days ago I had to run into town on some holiday errands and encountered this.
 

One of our resident bald eagles.  The bird casually allowed me to snap photos and even reposition the car on the road.  As I departed the bird did too.  I wonder if he/she deliberately allowed me the convenience of observation and study.  Naw.  That would be too much Disney-like anthropomorphism. 
 
Thirty years ago these weren’t as common as they are nowadays.
 
On the south side of County D a short distance from my front door…

Manicure or Pedicure

This is a common hawk around these parts and remarkably sometimes captured digitally on one of the trail cameras.  Like this one from the last batch of photos we recently uploaded.

Don't take my word for it; if you go to the 'LABELS' feature on the left side of the blog homepage you can click on Red-Tailed Hawk or Raptors to see previous posts on the subject.

This bird comes in a range of colors stretch from dark brown to almost white.  Typically they're shades of brown, white breast and a distinctive rust-red tail.  Both sexes are similarly-colored with the female being slightly larger in size.  Yes, you'll find photos here of a pair.  

They raise one brood a year and the young of the year don't develop the red tail until the second year.  Contrary to what the book says - this species is found here year-round.

Here's a captive (rescue) bird; providing a good look at the talons found on this  raptor.  

If a raptor goes to a nail salon do they get a manicure or a pedicure?

Backyard Circus

 

Audubon Image

Meet Circus cyaneus - the northern harrier - colloquially known as a marsh hawk. A predictable resident as we've been host to a nesting pair for any number of years already.

 
The genus name Circus comes from the Greek kirkos - meaning 'circle' a reference to its circling flight. Cyaneus is Latin - meaning dark-blue. 
 
This is an easy bird of prey to identify.  Northern harriers have several characteristics that set them apart from other hawks.  The feathers around their face have an owl-like disk focusing sound into their ears. Their wings form a v-shape as they fly low and slow and parallel to the ground during flight. Males have a white belly while females have a streaked brown belly.  They also have a distinctive white rump and black wing tips which are visible during flight. 
 
This raptor both nests and feeds on the ground and provides hours of bird watching as they hunt over the tall grass prairie north of the house.
 
I captured this video Sunday afternoon.  It was the second time I witnessed this behavior this week and fortunately had the presence of mind to have my device handy to record it.  A turkey has cutting thru the field out back and both birds were ganging-up on it to harass it and drive it off.  If I had to hazard a guess this is a display of territorial behavior.  It is not at all different from tree swallows dive-bombing me and the dog during nesting season.  Although I'm not going traipse thru there and test the hypothesis with the hawks.
 
Be sure to turn-up the volume....

Arctic Visitor

Meet Buteo lagopus - the Rough-legged Hawk.  Dark morph to be exact.

The raptor takes its name from the feathers that extend down the legs to the base of the toes - an adaptation to the cold environment this bird prefers.  This hawk is only seen here on the peninsula during the winter months with the southern-most extent of its winter range being the Texas panhandle.

Summer breeding range is the northernmost extent of Canada's coniferous forest zone and escarpment bordering the arctic tundra.  Preferring open country, when hunting this bird of prey often hovers on beating wings and at sustained speeds of 22-28 miles per hours it can fly for longer periods than most birds of prey.  In a dive it can reach speeds of up to 120 miles per hour. 

The light morph has a distinctive the white rump on the upper tail and underside is easily identified by the dark wrist patches on the flight feathers of the underwing and a dark band at the end of the under part of the tail.  (See photo below).  The dark morph is dark all-over.

Prey includes small rodents such as lemmings, voles, ground squirrels and other small mammals.  This species is monogamous and the female guards the nest while the male is on the hunt.  A pair will fledge 2-6 young once a year.    

That makes for two raptor appearances so far this year on a trail camera.  That's a good start.

Mystery Bird

From time-to-time one of the ever patient and vigilant trail cameras delivers a real keeper photo.  It might be an infrequent critter, an artfully-composed image or an action shot.  Every ten days or so as we make our rounds of the camera trap line can be an adventure.

Recently there was this.... 

It's a rare event to snag an image of a resident raptor on the ground.  Particularly one with another bird for scale.  In this case a crow.

I cannot be absolutely certain but I believe that the hawk is a female northern harrier. Underside wing markings, owl-like face and yellow eyes are reasonably reliable field marks.  Also, a male and female are frequent visitors and are observed hunting as they glide just above the ground in the breeze.  

Even if I'm wrong about the ID it certainly made my day to upload these gems.

The Eagle Has Landed


Side benefit of living in a wild land.       
 
If you look above the inspection pipe sticking out of our POWTS - in the center of the photo you can make out three bald eagles perched in a tree.       
 
The one on the bottom is a mature adult.  The two above are juveniles. The youngsters will attain the distinctive white head plumage at 4-5 years of age.        
 
This was a fortuitous observation.       
 
Should probably go out and purchase a lottery ticket....

Breakfast of Champions

Once and a while I'm fortunate to get a photo of a raptor on one of the trail cameras. This is not anywhere near as spectacular as the bald eagle photos from earlier this spring but it is interesting nonetheless.    
 
A red-tailed hawk. 
 
 
Over a period covering fifteen minutes the camera recorded this bird dining-upon its prey.    
 
 
I wonder if it was one of the fox squirrels photographed earlier at the same location.......

Fun Weekend

The First Mate and his wife paid a visit this weekend.  The Nightingale Supper Club knocked the ball out of the park with cocktails, steaks and prime rib.  

There were raptors to see at the Open Door Bird Sanctuary



Homemade pizza pie.


And taking the mule for a spin to check the trail cameras.


Life is good with good friends...

Animal Factoid

I was reading something the other day about three magnificent raptors – the barn owl, osprey and peregrine falcon. 

These hunters are quite adaptable, capable of flying vast distances and are specialized hunters.  The peregrine falcon preys-upon small birds.  The osprey fetches fish from the lakes and river it calls its habitat and the secretive barn owl subsists almost exclusively on rodents.   

All three of these birds can be found throughout the world - a testament to their adaptability.  Nevertheless, a successfully adaptable as these birds are they are not to be found on the continent of Antarctica.  Evidence that there are limits on adaptability.

Coincidentally, you will find ants and dung beetles on every continent as well.  With the exception of Antarctica.

Free Bird



If you’re like me the iconic image in your mind of the bald eagle is probably a majestic and noble raptor - a soaring patriotic symbol of freedom, liberty and America.   

For the inhabitants of the sleepy fishing village of Dutch Harbor, Alaska, the 500 or so bald eagles that they live with are nothing but pests.    Our great nation’s national symbol is a thief.  They steal bait from the fishermen, pick through trash, and snatch grocery bags from unsuspecting pedestrians.  The locals refer to them as Dutch Harbor pigeons.   

I think a good start to ending this bad bird behavior is to cease encouraging them.  Raising a toast to Lynyrd Skynyrd....

A Bird in the Bush

The robin nest that I posted last week featured two blue eggs.  I checked it yesterday and sure enough - they hatched.  And it is remarkable the size the little chicks have put-on in about a week - give or take.

On Sunday I knew momma was attending to her family when she darted from the nest as I walked past.  I didn't see her yesterday at all.  Which doesn't necessarily mean she's not around - only that I hadn't seen her.

I did find this in the yard - evidence of a robin nailed by a raptor...



Ugh.

Meal for an Owl

Photo taken by a trail camera with IR (infrared mode - no visible flash) of a bunny.  

click on image to enlarge

There were actually three photos.  A bunny, a blurry hopping bunny and this bunny.  It occurred to me that there is always the possibility of one of the cameras one day capturing a raptor pouncing on one of these members of the bottom of the food chain.

Bunny is a meal for an owl...

What's For Lunch

Ever find an owl pellet?  Check this out...


Most of the owl pellets I've found are in the 1.5 to 2 inch range.  The pellet above is longer than 4 inches.  It has got to be the Mother Of All Owl Pellets.

Owls are not able to chew their prey and unlike most other birds they do not have a crop for storing food.  Therefore, what an owl kills is passed directly to their digestive system.  The first chamber of the bird's stomach is called the proventriculus.  The acids and enzymes here begin the process of digestion.  From there the prey passes to the gizzard or ventriculus.  This functions as a way point for the holding of indigestible matter - namely fur, feathers, bones, etc.  Everything else passes through the small and large intestine to the cloaca and is ultimately expelled through the vent.  With the exception of the ostrich birds do not have a bladder so whatever is excreted from the vent is largely acid - the white substance that makes up bird poop.

Back to the ventriculus.  All of the undigested stuff now blocks the bird's digestive system so the bird cannot feed again until it is expelled.  Muscular contractions in the gizzard compress the contents into a pellet.and send back to the proventriculus from which it is regurgitated.  This may have come from a different bird of prey but either way I would have given anything to see the raptor that hacked this up.  Big pellet - big bird!

When I have some extra time I'm going to dissect this curiosity and see if I can learn more about the raptor's dietary choices.  I'll report back with my findings.

I hope this post got you thinking about what you're having for lunch...

Wisconsin Raptors

The king of the raptors.

The bald eagle - Haliaeetus leucocephalus - a magnificent bird that was almost driven to extinction as a consequence of DDT poisoning  this raptor has made an amazing comeback.

Hard to believe this woman can hold this huge bird with its huge talons...

Wisconsin Raptors

Red-tail hawk - Buteo jamaicensis - a hawk we see all the time around here.  As a matter of fact if you are driving up and down the highway this is the raptor you'll likely see perched on a fence post or road sign or tree. 

They're everywhere.

Individual birds will vary in color from one-another with a wide variety of shades of brown, copper, chocolate, white and grey.

Wisconsin Raptors

American kestrel - Falco sparverius - formerly known as the sparrow hawk.  It's a falcon for sure and is murder on grasshoppers, small birds, mammals and snakes.

This is a female - which has conspicuously different markings from that of a male.

Wisconsin Raptors

Great horned owl - Bubo virginianus - is one of the most adept of hunters.  Known as the Winged Tiger this bird can live up to thirteen years in the wild.

click on image to enlarge

No wonder.  It is blessed with excellent hearing allowing it to hear the movement of a rodent underneath a foot of snow.

The trailing wing edges are ragged allowing a silent and deadly flight as it seeks its prey.

Those tufts of feathers (or horns) are not ears. 

They're just feathers.

Wisconsin Raptors

Barred owl - Strix varia - a grey and brown owl with a large head and dark brown eyes.

A common forest owl it has a distinctive call...who cooks for you, who cooks for you, who cooks for you all...

They are often seen perched in a tree keeping a sharp eye out for voles, mice and other prey.
