It’s enjoyable to observe how birds behave within the deep snow

Surviving Maine’s winter appears really a exceptional feat for a lot of of our feathered buddies, however that’s from the attitude of a mammal with a big prefrontal cortex and a fire. Most birds are completely tailored for the chilly, and discovering meals is their major concern within the winter. With the latest deep snow storms, I wished to focus on a couple of attention-grabbing phenomena we see with our birds as they adapt to the worst of the winter.

I’ll begin with one in all my extra entertaining yard birds, the wild turkey. I’ve written about my love-hate relationship with them earlier than, as they tear up my yard all summer season to dig out sandy patches to take a mud bathtub in, but in addition carry their lovable chicks round and assist eat all of the ticks and bugs I don’t need. We are surrounded by tall white pines, which a bunch of 45 turkeys fly up into every night to roost. In the winter, we find yourself with a number of well-trodden paths that the turkeys take every day, slowly packing down the snow. After the deep snow of the large storm on the finish of January, we ended up with a number of the most spectacular canyons carved by the fluffy snow the place the turkeys have been plowing their technique to entry the street. I measured one of many paths at 14 inches to the snow, plus one other inch or so their toes would’ve sunk. That’s near half of the hen being within the snow. 

Turkeys are primarily floor feeders, and within the winter will usually search out wooded areas with dense cowl the place snow received’t be as deep. Here they will scratch by the snow and the leaf litter to uncover acorns and different seeds … except there’s a lot snow that they should lookup for meals. Twice, on the day instantly after the deep snow, I noticed teams of untamed turkey foraging in crab apple bushes. These massive birds are usually not actually constructed for maneuvering across the small branches of those fruit-bearing bushes, however they have been making it work, or a minimum of placing within the further effort for the meals that was nonetheless accessible. 

Winters will also be a difficult time for owls in Maine. Barred owls are sadly frequent as roadkill as a result of they get hit by vehicles whereas they’re going for the straightforward meal of a mouse working throughout the street. Road sides with quick mowed grass (and thus seeds) create an ideal habitat for rodents. Packed roads (and cement) are arduous for them to go underneath, in order that they change into weak to owls and hawks whereas they’re crossing above floor. Many of those shrews and voles will spend the winter within the subnivean layer, between the arduous floor and the highest of the snow. This is usually a secure place, besides that owls, whose listening to is so good that they will sense their prey by the snow, can punch by and seize the unsuspecting sufferer when the snow is shallow sufficient. 

Sometimes, nevertheless, this layer will be too deep for owls to successfully hunt, so we frequently get reviews of owls in unlikely locations after massive storms. At the top of January, we noticed a report of a long-eared owl, usually one of the vital elusive owls in Maine, sitting on a railing in a downtown Portland yard, close to a hen feeder. Unlike a Cooper’s hawk that goes for songbirds at feeders, the owl was extra probably going after rodents interested in spilled seed from the feeder. At the identical time, we received a report from central Maine of a boreal owl, even rarer than the long-eared, that was stalking a hen coop. Again, the owl wasn’t within the chickens (a barred or an excellent horned owl is likely to be, however boreal owls are smaller than most chickens), it was after the mice, who have been going for the hen feed. 

Feeder birds have been one more spotlight of this snowy storm. It is at all times entertaining to see the elevated exercise at feeders earlier than a storm hits. Many birds have built-in barometers and may sense when a storm (low stress) is coming in, in order that they’ll improve feeding forward of and through a storm. We additionally see elevated exercise at feeders following a storm as a result of that meals is straightforward to entry (as we talked about with the turkeys above). 

It is difficult to maintain observe of 1 particular person hen’s habits, however one which I discovered attention-grabbing not too long ago was a bullock’s oriole that has been visiting a feeder in Blue Hill. This is the western sister-species to our Baltimore oriole, and we’ve seen a handful of winter information in recent times, usually of people at yard hen feeders. This one was first noticed in November, and has been an nearly day by day customer (apart from a brief hole in the course of December). It stayed repeatedly till Jan. 11, then disappeared. Well, on Jan. 26, simply after the deep snow, the oriole was again on the feeders. It is enjoyable to consider all of the uncommon birds that could possibly be wandering across the state, not supplementing their weight loss program with feeders, simply going unrecognized. 

While the chilly temperatures and deep snow would possibly seem to be a downer, my hope with this text is to level out a number of the enjoyable issues you’ll be able to look ahead to in your backyards or in native public areas in winter. And in just some weeks, we are able to begin to anticipate a number of the earliest winged migrants coming again. What are you seeing this winter?
