Northern (Great Grey) Shrike in southwest Missouri
GREENE CO., MO — This morning Lisa Berger, Charley Burwick, and I wandered around the Osage Plains west-northwest of Springfield, Missouri. We found gobs of red-tails, kestrels, and harriers, but no Merlins or Prairie Falcons. We did pretty well with sparrows: Harris’s are always special, I don’t get to see American Tree Sparrows in north-central Texas, and we heard a Fox Sparrow singing.
But the day’s big excitement was a certain shrike.
From a distance, the shrike’s mantle appeared rather pale (”frosty,” Lisa said). Its mask seemed narrow, and the bill seemed long. All these features suggested Northern Shrike, but the distance was a little too much to be certain. Northern Shrikes are rare in this part of the state, and we didn’t want to make a sloppy call.
Happily, we didn’t have to wonder forever. As we sat quietly beside the road, the shrike worked toward us, eventually offering fantastic scoped views. Fine dark edges on the bird’s pale breast feathers produce a scalloped or vermiculated look at close range. Note too that only the lower half of the bird’s eye is within its blackish mask. And, the area immediately over the bill is whitish, not dark. Photo digiscoped by Charley Burwick.
Here you can see the bird’s huge, very strongly hooked bill, which is pale at the base. You can also see a pale whitish mark in the bird’s dark lores. The bird shows a square head and a distinct neck. (See more on Loggerhead and Northern Shrike ID.) This photo is also by Charley Burwick.
