What a face…what a face…(or beauty "in" the beast)

Our winter starlings have started visiting our feeders. (Oh, boy...right?) Actually, it's quite exciting when a flock descends on the yard. Hundreds and hundreds of birds swirl about squawking, scolding, and fighting...tree branches drip with the little feathered beasts, and I can hear them tapping across the gutters and on the roof. They bring in a lot of energy. Unfortunately, they eat up a lot of sunflower seeds, and they wreak havoc on the less rowdy birds that usually hang out. We have starlings year round, but they only become a nuisance during the winter when the ground is frozen. During the spring, summer and fall they keep to the ground, using their sharp bills to dig in the yard and root out grubs. They only get a little "beastly" during the winter...

I'm back, so you better get used to me!

When you step back from the “ucky stuff” they do, European Starlings are striking. Up close you can see their beauty, and they actually do a lot of good on the insect front. Invertebrates are their primary food source, and when bugs are available, European Starlings really do prefer Japanese Beetles to sunflower seeds...

Don't hate me because I'm beautiful...

Grumpy, Grumpier...and Grumpiest
There are no Japanese Beetles in winter, and the June Bug grubs have burrowed beneath the frost line, so what's a starling to do? Be grumpy...and eat all of the sunflower seeds!


When the sun highlights their iridescent colors, they really are eye catching, but unless you look closely, you might not see it. Additionally, in the winter, their feathers are fresh and new, which adds a beautiful speckled pattern. By summer the speckling has worn off...

...another bit of beauty starlings add to the world is their incredible winged ballet. A huge night-time starling roost is about a mile from our house, so in the early evenings of winter, we get to witness this spectacle…swirls and turns, a giant black cloud that moves at incredible angles quickly and without pattern...it makes me stop and stare every time I see it. Click here for a video from England that shows an example of this incredible sight. Click here for a post titled "How do Starling Flocks Create Those Mesmerizing Murmurations?" on Cornell's Round Robin blog by Andrea Alfano detailing these murmurations.

...so while the ground remains frozen and covered with snow, we will probably always be a daytime roost for one of the flocks of starlings from our neighborhood night-time roost. 


I always try to remember that with the bad comes the good. We don't use pesticides on our lawn, so in the summer, starlings go to work for us. They are great at aerating the soil by digging up White Grubs (the larval stage of "June Bugs"), Sod Webworms, and other juicy invertebrates, which helps keep our lawn healthy.  The US Department of Agriculture's Farmer's Bulletin (1928) No1571 reports, "The starling is one of the most effective bird enemies of terrestrial insect pests in this country. More than half (57 percent) of the annual food of the adult starling consists of animal matter, including insects, millipedes, spiders, mollusks, a few crustaceans, and bits of suet and carrion."

Happy Birding!

A Winter Starling Roost is Near our Neighborhood

I pulled into the driveway at home this evening to quite an impressive sight. A huge, ABSOLUTELY HUGE flock of starlings was swarming around the neighborhood in great clouds. This happens every now and then because our neighborhood is about a mile from a massive winter starling roost. In the evening, the birds all gather in the huge trees just off the field between Rt. 741 and Courseview. The noise is incredible and the sight is magnificent (whether you like Starlings or not, the sheer energy of all those birds is extraordinary). About two weeks ago, as Matty and I pulled into our driveway, the center of a massive flock seemed to move around us. Waves and waves of dark feathers and bird bodies swooped back and forth in constant motion, alighting for a second in trees or bushes or roofs and then bursting back up. We just sat there and watched them in awe. It lasted about 2 or 3 minutes before the swarm started moving down the street. It’s a great memory neither of us will forget.

A small part of the flock used my
neighbor’s roof as a temporary roost.

Why don’t they flock like this in the spring or summer? Starlings still flock then, but their numbers are lower. The smallest flocks are in the spring during the breeding season, and the largest in the winter when the flock takes in migrants from the north. Here is a helpful article on roosting and starling behavior.
