Lowell to Lawrence along the Merrimac River 1/9

Saturday, 1/9/2010, I checked out the recently reported Red-headed Woodpeckers, in Tyngsboro, Ma., just outside of Lowell. The juvenile bird was rather cooperative, though at a distance, while the adult did not show until I was about to leave. The juvenile bird's head is begining to develope some red at the base of it's nape, see the digi-scope shot below.

After "taking in" the woodpeckers I decided to bird along the Merrimac River from Lowell to Lawrence. There were plenty of Gulls and Mallards at the UMASS boat house, I soon found out why, as a man showed up toting a rubbish bag of bread. He was soon decended upon by about 200 Rock Pigeons, 50 gulls and a few Mallards.
This bird, a 2nd yr. Herring Gull was "chummed in " by "bread man", here is the DRC info on this bird:

Looks like he was seen there last spring, in the same spot. He knows where the food is.

Incidently, the capture site of this bird is where I do my grocery shopping.

Near by, I saw the Great Black-backed Gull pictured below, with a swollen foot, I had also seen a Herring Gull with a similar ailment. Disease, Frostbite.....?

Thats gotta hurt.

I made a few stops, along the river, on my way to Lawrence, at one I found 75 Mallards, a few Black Ducks, 3 Wood Ducks and 125 Common Goldeneyes. I was able to pick out one female goldeneye with a yellow bill and was thinking I'd found aBarrow's, but head and bill shape was more fitting for a Common Goldeneye. From a little research, Common Goldeneye females can have a yellowish looking bill, though rare. Non-the-less an intersting bird, but Barrow's didn't make the check list.

Once in Lawrence, I saw 2 adult Peregrine Falcons near the clock tower, one was "mixing it up" with a Red-tailed Hawk, that might have infrindged upon the falcon's territory.

I ended the day at the boat ramp in Lawrence, just above the dam, there were many gulls and crows on the ice. I was greeted by a group of domestic ducks as I opened the car door.

What...insurance salesmen?

A few of the better birds were a Great Cormorant and an adult Iceland Gull, pictured below. It was late in the day, and large numbers of crows were coming to roost in the general area. I was fortunate to hear at least a few Fish Crows.

The Iceland Gull soon disappeared, then an older guy showed up with rubbish bag and began "slinging" bagels. In with the dozens of Ring-billed and few Herring Gulls was a 2nd year Glaucous Gull, which easily out muscled the others.

Waiting...........

Some one's about to get WUPPED and I know who my money is with.

Just a small portion of the crows passing to roost.

The river was lined with crows as far as I could see up river and more were moving along the horizon as I scanned down river. My crude estimate ( and probably on the "light" side, but you get the idea) was about 5,000 , though I recall the late Joe Hogan mentioning numbers from 10,000 to 15,000. Joe had always birded the Lawrence area, keeping an eye on the local Peregrines, the crow roost, passing Nighthawks and of course finding the huge blackbird roost in Methuen...sure wish Joe was still with us.
