Mystery Bird: Eastern Bluebird, Sialia sialis

Don't think there's any doubt here- a female Eastern Bluebird, Sialia sialis: reddish-brown throat, while belly; bluish-grey crown; hint of blue on the shoulder...

Differentiated from the Western Bluebird (Sialia mexicana) and the Mountain Bluebird (Sialia currucoides), the females of both having grey throats and grey bellies (and both possibly out of range anyway)...

as far as subspecies are concerned, there are 8 proposed:

sialis, southern and southeastern Canada and eastern US south to northeast Mexico;

fulva, southwestern US (southeastern Arizona) south through montane Ccentral Mexico;

grata, southern Florida;

bermudensis, Bermuda;

nidificans, Caribbean slope of east-central Mexico;

guatemalae, southeastern Mexico (Chiapas) and Guatemala;

meridionalis, El Salvador, Honduras and northern Nicaragua;

caribaea, eastern Honduras and northeastern Nicaragua.

Notes include:

occasionally hybridizes with S. currucoides; geographical variation slight, and level of individual variation in morphology and behaviour within and between populations remarkably high; in addition, lack of a "prealternate" moult results in very worn birds in spring and summer, confounding racial analysis and attribution; bermudensis, grata and meridionalis possibly untenable; proposed race episcopus (S coastal Texas, in USA, S to S Tamaulipas, in NE Mexico) considered indistinguishable from nominate

Well that's interesting ... not the bird so much, likely a bluebird ... but that I can see the picture. In your blog posts it is pretty much a sure thing that your pictures don't show up on your page and I can only see them if I use the link to the larger version to download them separately.

This is not a problem with your Sblings so there is something odd about your code or the way my browser, Mozilla FF, handles it.

But this time I see the bird, something of a novel event so I figured I'd ask. What did you do differently this time? And, can you keep doing it?

Art, I have the same problem at work but not because of the browser- I can use Explorer or Mozilla but the DC Government net appears to prevent pictures on many sites- at home I use Explorer and have no problem... I assume that some security protocols concerning spam or adware are responsible...

Thanks for the insight David @4.

I suspect that the pictures that fail to show up are on another server and something about how they are addressed fails to retrieve them. I suspect that David is right that some detail of of the network might be conflicting with the details of how this blog handles the links. Might be interpreting the way the link is handled as an attempt at spoofing or other nefarious activity.

Something about how the link is handled must be rather unique. Visiting a lot of other sites this blog is the only one I'm having this sort of issue with.

i host all my images (except my banner, which is hosted by SB) at flickr. this is something i started doing for my blog when i started writing at blogger since that site originally did not host images. to the best of my knowledge, i am the only one at scienceblogs who continues to do this, and considering the huge amount of space my images fill each month, it's probably a good thing for SB, too. but your problems viewing images are strange .. has anyone else had problems viewing my images?

Ahh, I forgot about the way embedded stuff gets hosted- the problem is indeed Flikr... at work access is denied to sites that could also involve social networking, so directly going to youtube, or facebook, or flikr, etc. is always prevented- in this case, loading the photo on your blog (and funnily enough scienceblogs is one of the few blog sites that is not routinely blocked) the photo still "asks" he server for access to the same unapproved site

Thank-you "GrrlScientist" for you insight and attention. Interesting, I'll root round my comp and see if flikr is disallowed by some hidden rule. Seems odd that I was always able to download the larger version of the picture from flikr if flikr was blocked. Or that previous blog posts hosted on flikr didn't download from the page, and now they do. Curiouser and curiouser.
