This leucistic redtail has been sitting on her nest for some weeks, and now she appears to be feeding young.

Instead of being nestled down into the nest, we see her sitting more erect, as she is in this picture. Often she’s on the edge of the nest, peering down, probably giving tiny bites to tiny beaks.

It’s interesting to see the fresh greens she has apparently added to the nest. I know Big Red did the same thing in the Cornell hawk nest we observed a few years ago too, though I’m not sure what the purpose is.

It’s been awhile since I’ve seen the male, so I hope he’s all right. At this stage, there’s plenty for both parents to do.

We’ve been keeping an eye out for the leucistic redtail in our neck of the woods. Our sightings are fleeting, but we’ve accumulated enough of them to construct a narrative at this point.

Usually the hawk is far away, and she has a knack for choosing unphotographable areas. We call her Marley, after the ghost in A Christmas Carol, because of her whiteness. We think of her as female because she is larger than the more typically colored redtail we see her with.

See what I mean about unphotographable areas? Cropped in, though, you can see that this is a pair of hawks.

Lately, we’ve been seeing Marley near, and sometimes perched on, a nest.

So it looks like her story goes something like this so far: Marley has paired up with a male, and she is getting ready for nesting season. We’re not positive yet that she’s actively using it, but if so this is by far the most unusual nest we know of. We look forward to observing whatever we’re able to see over the next few months without scaring her away from her maternal duties.

We’ve seen this large, snowy white raptor several times nearby since around November.

Naturally, I’ve thought it was a snowy owl. Last year snowies were on everyone’s radar because it was an irruption year, and I figured this might be one of the surplus young who were born in the year of plentiful lemmings.

We saw it about a week ago being mobbed by crows, and it was so large, and so white, I thought again: snowy owl! But…

Yesterday it was sitting in and near an old red-tailed hawk’s nest, vocalizing like crazy, and I got a couple of better (or at least, closer!) pictures.

Clearly not a snowy owl!

I noticed several things. It was not an owl call; it was the classic red-tail’s scream. (Another hawk answered from farther away!) It didn’t have yellow eyes. It didn’t have feathered feet. And it just didn’t have the blunt owl body.

Could there be such a thing as an albino red-tail? Searching online, I discovered there could — though the word in this case is not albino, but leucistic — partially albino. The eyes, after all, are not red. And there are some dark accents in the feathers.

We were tickled to have a snowy owl, but we’re even more tickled to have a rare hawk. At first I was sad, thinking its chances of survival would be poor without the protective coloration. But it’s already survived the winter, so its survival skills are pretty good. There aren’t that many predators to worry about. And a dense leaf canopy would hide it well enough from prey below.

As for being chased by its own kind as an enemy, well — it surely did seem to be conversing with that second hawk, and perhaps readying the nest for breeding season. So we’ll see. There is at least this picture online of a leucistic red-tail on friendly terms with a more typical one, so I have hope.

My daughter named it Marley, after the ghost in A Christmas Carol.
