Tucson & Saguaros

Now that my sister & bro-in-law have a winter home in Tucson, AZ, the cat & I travel down for a yearly visit ... 

It was about this time last year, Freddie & I set off.  It takes 4 or so days to drive (less if Freddie could take a shift at driving, but refuses to even try - isn't that just like a cat!)  We endured very strong winds from the South Dakota through to the Oklahoma panhandle, then snow in northern Arizona but finally reached the place where saguaros grow.


Both Cactus Wrens and Gilded Flickers use saguaros for nesting


The more arms, the older the saguaro


And eventually, like all things, these desert giants die


The skeletons of a fallen saguaro, with a nest

 
Not kidding the spines are strong and sharp!  Somebody put this rock on top of a young saguaro along the path. 


 
We're going back this year...soon.

The Zen Of A Rusty Hinge

Xanthocephalus xanthocephalus or Yellow-headed Blackbird or as Pete Dunne calls it 'Saffron-hooded Cacophony'.  Sums it up.


Nothing is more entertaining than watching a male YHBL puff out his chest, spread the tail feathers, hunch out his wings, throw back his head and let loose with....a sound almost exactly like a very rusty old gate opening for the first time in years.


These boys are unmistakable and very common out here in the western side of the continent.  Years ago, I was birding at Delta Marsh at the bottom end of Lake Manitoba.  The south end of the lake is bordered by a small collection of deciduous trees and a vast wetland full of reeds, cattails and phragmites.  I was jubilant having just seen my first Blackburnian Warbler.  I met a young couple on the marsh boardwalk who were acting equally as jubilant.  We shared our exciting news.  They were from Ontario and had just seen their first Yellow-headed Blackbird.  Yay  (Blackburnian Warblers nest in their yard).



I grew up with the birds and frogs of prairie sloughs making joyful racket.  When I want to clear my thoughts, exorcise my worries, achieve my particular state of zen, I wander off to the nearest cattail marsh.  

Yellow-headed Blackbirds are among the first birds to return in Spring, staking out their territory in the marshes.  A late season snow will bring the blackbirds into town to scrounge at the seed feeders.  


The female of this species is a mostly brown bird, with some yellow on the brow, face and upper breast, some white streaks on lower breast.  Immatures are similar.  The females build nests on the emergent vegetation, the nest is always placed over deep water. 

Unfortunately, I haven't got a decent photo of a girl YHBL to post so here is another one of buddy, throwing his head back in mid-sqwak. 


Apparently there have almost always been Yellow-headed Blackbirds.  Cool Fact from All About Birds:
Pleistocene fossils of Yellow-headed Blackbirds (from 100,000 years ago) have been dug up in California, New Mexico, and Utah.

World Wetlands Day

Today, February 2nd, is 

1.  Groundhog Day.  We are in the middle of cold and snowy winter where I live, so rodents of any size are still deep in their hibernation and no amount of silly human intervention is going to prod any of them out of their dens.

2.  Superb Owl Day.   Although I am a football fan, I don't really care who wins the Superb Owl - or Super Bowl as some like to call it - today. 

3.  World Wetlands Day.  The local wetlands are also frozen over and will be for some time to come.


I love prairie sloughs where Marbled Godwits


Black-necked Stilts


and tiny baby Sora rails can been seen if one is lucky.


A large slough will be home to ducks, geese, large wading birds maybe even a  White-faced Ibis


a flock of dowitchers


 or an American Bittern


and a million other species of organisms.   

Please appreciate your local wetlands.  Thanks.

Meet Emission Nebula NGC 6188

I've never really been a 'night person'.  I go to bed early and I get up at Insane O'Clock in the morning.  I love my mornings.  Therefore,  I can't seem to convince any part of me that it would be a terrific idea to get up in the middle of the night - even on a warm summer night - to go outside to look at the stars.  True, it is dark when I get up; however, unless I am going on a birding excursion, my early mornings are dedicated to coffee, playing with my cat, reading, blogging and other internet-involving stuff.

So, I look at the NASA site most mornings to get my 'self-importance' bearings - you know, just in case I start thinking any worlds revolve around me, etc. etc. etc....


NGC 6188 and NGC 6164

Explanation: Fantastic shapes lurk in clouds of glowing gas in NGC 6188, about 4,000 light-years away. The emission nebula is found near the edge of a large molecular cloud unseen at visible wavelengths, in the southern constellation Ara. Massive, young stars of the embedded Ara OB1 association were formed in that region only a few million years ago, sculpting the dark shapes and powering the nebular glow with stellar winds and intense ultraviolet radiation. The recent star formation itself was likely triggered by winds and supernova explosions, from previous generations of massive stars, that swept up and compressed the molecular gas. Joining NGC 6188 on this cosmic canvas is rare emission nebula NGC 6164, also created by one of the region's massive O-type stars. Similar in appearance to many planetary nebulae, NGC 6164's striking, symmetric gaseous shroud and faint halo surround its bright central star near the bottom edge. The impressively wide field of view spans over 3 degrees (six full Moons), corresponding to over 200 light years at the estimated distance of NGC 6188. Narrowband image data has been included in the natural looking color composite, adding to deep red emission from hydrogen and sulfur atoms and the blue-green light of oxygen atoms.

Squeerrrllls

One morning last May, a couple of very young Eastern Fox Squirrels (Sciurus niger) were fooling around in the elm tree outside my kitchen window.  There were four altogether, the other two were less independent and were staying close to their nest in the tall spruce at the other side of the yard.


So much fun racing around the branches on a warm spring day.


These little mutts were about 30 cm/12 inches long, from nose to tip of tail; about half the size of an adult. 


Very cute.

A Somewhat Famous Bird


So what's famous about an Eastern Phoebe (Sayornis phoebe)?

It isn't fabulously coloured.  Rather, it definitely fits in the ubiquitous 'lbj' category (little brown job) of birds.  Overall drab, medium-sized flycatcher, grey-brown uppers, pale whitish-yellow unders, maybe a bit more yellow on the belly, no eye-ring, no wing bars, black bill and legs, long tail.  Largish head.  Sexes similar.  (Yawn)

There are a couple of things about this bird, though, that make it quickly identifiable.  It sits perkily upright on its perch, and its tail is usually in motion, pumping and wagging.

And because it is a flycatcher, its mode of operation is to perch on a branch, sally out to snap up an insect, return to perch (or take tasty morsel over to nest to feed one of the 4-5 youngsters raised yearly).  If near water, they will pluck insects and aquatic invertebrates off the water surface.

 

Eastern Phoebes don't winter very far south, so are one of the earliest returning songbirds birds in spring.  This fact alone makes it one of my favourites.  Nothing is as joyful sounding in mid-April, as a snappy "fee-bee" coming from the bushes near a low bridge over the river.  "Hello, I'm back!"


Another fairly unique thing is that Eastern Phoebes have adapted better than many species to the steady removal of natural habitat and the building of man-made structures.  Nowadays, they typically place their mud-and-grass nests in protected nooks on bridges, barns, and houses, preferably near water. 

Consider yourself lucky if one should decide to build on your property.   Excellent natural insect control.  Also, please don't destroy the nest at the end of the season as the bird will probably return to it the following year.


Now we are coming to the Somewhat Famous bit....

In 1804, John James Audubon tied a silver string to the leg of an Eastern Phoebe to see if it would return to the same nest site the following year, thus becoming the first bird to be banded in North America.

White-breasted Nuthatch

This is another of our little birds of winter.  Like chickadees, nuthatches are year-round residents here. It is always a pleasure to see one hitching down the trunk of a tree, head-first.

The White-breasted Nuthatch (Sitta carolinensis) is the largest of the four North American nuthatch species.  Their habitat is deciduous and mixed deciduous-coniferous forests and treed residential areas (that's me, waving hands).

Pete Dunne describes this bird as "a chunky, neckless, child's fist-sized wind-up toy of a bird...."
 

Nuthatches get their common name from their habit of jamming large seeds and nuts into tree bark, then whacking them with their sharp bill to “hatch” out the seed from the inside.  

White-breasted Nuthatches store food in cache sites with each storage place containing only one type of food.


Nuthatches do not use their tails for stability as do woodpeckers and Brown Creepers.  Instead, one foot is used to brace the bird against the tree, the other foot holds onto the bark.

Remembering a Summer Day

I suppose it is warm somewhere today - it isn't here.  I'm not leaving for my winter vacation for another six weeks and I'm tired of looking out the window and seeing white (as in snow).

What better time to sort through the files of downloaded photos from the past year?  Let's see what happened on June 26th.  Ah, yes, I went for a drive around my area.

One of the very frequent trains on the Canadian Pacific Soo Line; this one coming up from the US, looks like a shipment of new cars and trucks.  One of my favourite birding locations is just to the left - Roche Percee Park.


It is always a good day when I find a Cattle Egret (Bubulcus ibis)  gracefully moving through the shallows of a prairie slough.

  
Looks like a big storm brewing 'over East'.

 
Ah, the memories of a warmer time.

Happy 2014!

Happy New Year, Everyone!  And, what better way to start a year than a post about my favourite little birds - Black-capped Chickadees (Poecile atricapillus)


Who hasn't held out a handful of sunflower seeds, hoping a friendly, curious little chickadee will momentarily perch on a finger while taking a seed?  Or, smiled on hearing the familiar chickadee-dee?  (I suppose the non-nature lover types haven't, but those people aren't likely to be here reading anyway).



As familiar one is with this perky little bird, All About Birds has some Cool Facts, you might not know.  

- The Black-Capped Chickadee hides seeds and other food items to eat later. Each item is placed in a different spot and the chickadee can remember thousands of hiding places.

- Every autumn Black-capped Chickadees allow brain neurons containing old information to die, replacing them with new neurons so they can adapt to changes in their social flocks and environment even with their tiny brains.  

(It is quite probable that I, too, have allowed my brain neurons to die en masse, yet don't seem to have replaced them.  I do not recall much of anything useful anymore and don't adapt as easily to change as I used to.  I certainly wouldn't remember where I stashed any great number seeds.  Oh, to be a 'tiny-brained' chickadee!).

- Chickadee calls are complex and language-like, communicating information on identity and recognition of other flocks as well as predator alarms and contact calls. The more dee notes in a chickadee-dee-dee call, the higher the threat level.


- Winter flocks with chickadees serving as the nucleus contain mated chickadee pairs and non-breeders, but generally not the offspring of the adult pairs within that flock. Other species that associate with chickadee flocks include nuthatches, woodpeckers, kinglets, creepers, warblers and vireos. (No warblers or vireos in winter here in the Canadian prairies - not for long, anyway.)

- Even when temperatures are far below zero (F), chickadees virtually always sleep in their own individual cavities. In rotten wood, they can excavate nesting and roosting holes entirely on their own.

- Most birds that associate with chickadee flocks respond to chickadee alarm calls, even when their own species doesn’t have a similar alarm call.


Pete Dunne's Essential Field Guide Companion is just about my favourite birding book and constant reference tome.  BUT, I must take issue with Mr. Dunne in regard to his comments about Black-capped Chickadees.  He describes them as: portly and robust.  All right, that's fair enough.  However, when comparing them with the Carolina Chickadee he says:
 "Black-capped is a larger, more contrasting, more disheveled-looking chickadee than Carolina"
and 
"Black-capped looks like a scruffy ruffian of a chickadee; Carolina looks like a nice, well-groomed, well-bred chickadee"
Oh, puh-leese.  Those Southern Belle Chicks wouldn't last a minute Up HerePfffttttt!

Intergrade Northern Flicker

I have had two Northern Flickers (Colaptes auratus) coming to my feeders today.  One is a Red-shafted female, which is unusual for my area as I live in the eastern prairies.  The other flicker is this one.


This is a hybrid or intergrade male, with the grey-crowned head and facial colouring of a Yellow-shafted, but with the red moustache of a Red-shafted (black in a Yellow-shafted)



There's a hint of the Yellow-shafted's red crescent at the nape



 
And, for the heck of it....flicker tongue!

 
I heard this fella singing/calling from a neighbour's tree when I went outdoors earlier to fill feeders.  Very shortly, the Red-shafted female joined him.
