Loggerhead Shrikes – A Color Change I Don’t Understand
I’m confused about a color change I’m seeing in Loggerhead Shrikes. 1600, f/7.1, ISO 640, 500 f/4, 1.4 tc, natural light, image taken 4/26/13 on Antelope Island For most of the year the adults I see have a white or pale ventral surface (belly, breast and sides) which is exactly as described in the field guides and other resources I have access to. 2500, f/6.3, ISO 640, 500 f/4, natural light, image taken 7/3/13 on Antelope Island But beginning in about early July there’s a fairly dramatic change that is not addressed in my field guides. That white plumage turns significantly darker and an almost black area on the upper breast appears. This is about the time they’re fledging chicks around here and when I first noticed this several years ago I wondered if the birds were simply becoming “dirty” as they scurried around trying to feed and care for those very demanding youngsters. But now I’m pretty sure that’s not the case. All of the adult Loggerhead Shrikes I see go through this change to some degree or another. 3200, f/5.6, ISO 640, 500 f/4, 1.4 tc, natural light, image taken 7/14/13 on Antelope Island Here’s another (pretty silly looking) example. This is also the time of year when these birds are molting so I wondered if I was somehow seeing black skin (some birds do have black skin) through very skimpy plumage that time of year and I was somehow mistaking it for black feathers. But as you can see in this preening, molting adult, their skin…

Green-tailed Towhee
As I mentioned on this blog a couple of months ago I’ve been after quality images of the Green-tailed Towhee for years but they’ve always eluded me. This species has a special place in my heart and memory because it was my field project study species back in 1969 when I took a college ornithology class at the University of Utah from the legendary Dr. William H. Behle. That class provided the inspiration for my almost life-long love of birds. I’ve been trying to get some nice images of them for years now but their secretive nature and my bad luck always got in the way.

I love the half-closed, fuzzy eyelid and the ear tufts or “horns” that are just beginning to form on this young owl.
An Unlikely Alliance To Save The Greater Sage-Grouse
The Greater Sage-Grouse is a spectacular bird in many ways. They’re our largest grouse – males may approach 7 lbs. The dramatic breeding display of the males on the lek is mind-boggling. And to have one of these birds flush at your feet is literally a heart-stopping experience – something I know from experience.
But these birds are in great danger of extinction due to dramatic loss of habitat.

Some Hope For Barn Owls
I’ve reported previously on this blog that Barn Owl populations took a huge hit this past winter in northern Utah. It was dreadfully cold for much of the winter with lots of snow. Normally that’s not a huge problem for these owls but with deep snow on the ground we had a warm spell that melted the surface of the snow and immediately after that we had an extended cold snap. Those conditions caused a hard crust of ice to form on the snow surface that lasted for weeks.
Fledgling Loggerhead Shrike Begging For Food
I photographed a family of very cooperative Loggerhead Shrikes last week on Antelope Island. The young birds had already fledged and were very actively exploring their world, strengthening their wing muscles by flying from perch to perch and testing a variety of objects for their potential food value.
And they were gutsy! Several times a juvenile landed on the tailgate of my pickup as you can see here.
