RATS, RATS, AND MORE RATS! SNOWY OWL HEDWIG WEEKEND UPDATE #2

Hedwig was observed Saturday morning, when repeated harassment by a flock of crows sent her hiding. She reappeared Saturday afternoon, and was again seen Sunday morning in the drizzle, not too far from where she was perched Saturday evening. Later Sunday afternoon she slept and rested in the pouring rain.

That she stays in a highly localized winter territory seems in keeping with known Snowy Owl behavior traits. I read that during the summer season in the Arctic, male Snowies hunt over hundreds of miles, whereas female Snowies typically hunt within a much smaller range. She has been observed eating sea ducks and rabbits and there are plenty of rat holes along the backshore rocks.

Both rats and lemmings (the Snowies super food in the Arctic) belong to the order Rodentia. From wiki, “A lemming is a small rodent usually found in or near the Arctic in tundra biomes. Lemmings are subnivean animals. They make up the subfamily Arcicolinae together with voles and muskrats which forms part of the superfamily Muroidea which also includes rats, mice, hamsters, and gerbils.”

Often Hedwig has been seen flying straight out over the water towards Twin Lights. I wondered, if she is hunting there, does Thacher Island have a rat population. Thacher Island Association president Paul St. Germain answers that question for our readers, 

“Hi Kim, there are lots of rats on Thacher mostly in the shore line rocks. We don’t see them often but know they are there. I discovered a bunch in the cellar of the keeper house making their nest in an old tarp. I would love to see Hedwig out there but we don’t go out in the winter. Have never seen snowy owls in the summer.” 

Great info and thanks to Paul for sharing that! A Snowy Owl has been seen on the rocks in Rockport, across the strait, opposite Twin Lights, and wonder if it is our Hedwig.

This brings up the topic, what to do if you have a rat problem. The absolute worst way to control rats is with rat poison, namely for the sake of beautiful predatory birds such as Snowy Owls, falcons, hawks, and eagles. Birds that ingest rats that have been poisoned with rat poison will generally become gravely ill and die. Secondly, it is a cruel, slow death for the rat. They will usually go back to their nest to die. If that nest is located behind a wall in your home, you will smell that unmistakeable horrendous smell for many months. Thirdly, rat poison is only 60 percent effective. I wonder if the rats that survive rat poison will go on to breed super rats.

The best way to avoid having to kill a rat is to make sure they cannot gain access to your home or business by regularly inspecting soffits and woodwork for holes. Old-fashioned snap traps and live trapping continue to be the most effective way to rid your home or business of rats.

Saturday I stopped to say hello to a group of birders flocked together along the backshore who had traveled all the way from western Mass. They were observing Grebes, Buffleheads, and a Common Murre. And a Puffin had been spotted! I asked if they were planning to go to any of our local restaurants for lunch, but they had packed lunches. One Mom shared that an expert from Audubon told the group that there were at least a “dozen Snowy Owls” on Bass Rocks. Bananas! I have to say that it makes me hoppin’ mad when folks spread misinformation about our local wildlife. I gently told her that no, there were not a dozen owls, but that if she and her group waited until late afternoon, they might catch sight of Hedwig.

A Glorious Good Morning To You!

GLORIOUS GOOD MORNING BROUGHT TO YOU BY TWIN LIGHTS!

“It was a good one this morning,” some old gent walking past me remarked, smiling from ear to ear. Yes, I concurred, equally as full of joy to see the day begin on such a note.

CAPE ANN LIGHTHOUSES SHROUDED IN SEA SMOKE

Evocative views looking through sea smoke along the shoreline this morning, from Ten Pound Island to Twin Lights, and at every vantage point along the way. On my very last stop photographing a buoy in the sea smoke, I spied a mystery bird far off shore. Bobbing in the water and with a bill not at all shaped liked a seagulls, it was a SNOW GOOSE! He was too far away to get a great photo, but wonderful to see nonetheless!

New Short Film: The Uncommon Common Tern

What fun to encounter a small flock of terns teaching its young to fish. Nearly as large as the adults, the tubby terns cheekily squawk and demand food (shrimp I think in this case). Watch as the fledglings try to master fishing skills while the adults tirelessly guide the young on how to feed themselves.

With many thanks to Paul St. Germain, president of the Thacher Island Association, for information about the ongoing restoration of shorebirds on Thacher Island.common-tern-fledgling-feeding-copyright-kim-smith

There is nothing common about the uncommon Common Tern. They were named Common because hundreds of thousands formerly nested along the Atlantic Coast. As with many species of shorebirds, the rage for wearing fancy feathered hats during the 1800s nearly drove these exquisite “swallows of the sea” to extinction. After the Migratory Bird Treaty Act was ratified in 1918, terns began to recover.

A second major setback occurred when in the 1970s open landfills were closed, displacing thousands of Herring and Great Black-backed Gulls. The aggressive and highly adaptable gulls resettled to offshore nesting sites used by terns.

Common Terns are a Species of Special Concern in Massachusetts. Through a statewide long-term commitment of restoration, protection, and management of nesting colonies, the populations are very slowly and gradually increasing.

Former nesting sites include islands such as Cape Ann’s Thacher Island. During the mid 1950s, over 1,125 pairs of Arctic, Common, and Roseate Terns nested on Thacher Island. Today there are none.

The southern side of Thacher Island is owned by the Thacher Island Association. The northern end of Thacher Island is owned by the U.S. Fish and Wildlife Service, under the authority of the Parker River National Wildlife Refuge. These organizations are working together to restore terns and other species of birds to Thacher Island.
