"Peter! Peter! Peter!"

After easing in like the meekest of lambs, March assumed a decidedly leonine nature a few days into the month. The almost freakishly warm weather we had for the closing days of February that took away much of the snow that hit around Valentine's Day, was replaced by days that started out with temps in the single digits and did not warm beyond the mid-teens. As I walked out to the end of the drive to retrieve our newspaper on the coldest of these mornings I was cheered, but not really surprised, to hear the sounds of "Peter! Peter! Peter!"¹ coming from the tangles of honeysuckle and bittersweet that fill the area between our driveway and the private road that parallels it. It was the song of a Tufted Titmouse, a somewhat larger cousin of the Black-capped Chickadee, our Maine state bird.

Titmice are always among the first birds to begin singing in the run-up to Spring. This was not even the first time I'd heard one this year. That had happened nearly a month earlier--on February 10, to be precise. On that occasion I was out shoveling newly-fallen snow from the network of paths that connect our several bird feeders in the yard on the side of the house. There was still some snow drifting down. I soon worked up a bit of a sweat--this had been a wet, heavy snowfall--and stopped to rest for a couple of minutes. As I leaned on my shovel, trying to catch my breath, I was delighted to be serenaded by the sweet sounds of a Titmouse, Petering away in the woods. That time I was surprised, as this was the earliest I'd ever heard one. My previous first-of-year (FOY) record of a song had been February 16, 2011, the date on which I recorded the sound file in the above link.

Titmice are ubiquitous, year-round denizens of our yard and the woods that surround our house here in southern Maine. Along with Chickadees, Mourning Doves, Blue Jays, Downy & Hairy Woodpeckers, White-breasted Nuthatches, and Goldfinches, they're one of the species of birds we can almost always count on seeing whenever we look outside, regardless of the time of year.² They're handsome, endearing little critters. With their round, black eyes, short beaks, rusty-orange flanks, and prominent crests, they can only be described as "perky." They are frequent patrons of our feeders. Like Chickadees, they customarily select a single seed with each visit to the feeder, and fly off with it to a nearby branch where they crack it open and eat the nutmeat. They then make a return trip and begin the process all over again. Rinse, repeat. They are perhaps a bit more suspicious of human presence than are Chickadees, but in general they seem quite comfortable sharing habitat with us large, invasive bipeds. And we are certainly happy to have them do so!

As common as Titmice are here now it's sometimes hard to remember that things were not always this way; they are a relatively recent addition to the avian biota in Maine. And in the rest of New England, for that matter. They were seen only rarely, if at all, in western Massachusetts when I was growing up in the 1950s and '60s. It was not until I moved to Tennessee in 1985 that I became acquainted with them.

They are absent from early 20th century books on birds in Maine. Olive Thorne Miller makes no mention of them in With the Birds in Maine (1904), nor does Bates College student Carrie Ella Miller in her Birds of Lewiston-Auburn and Vicinity (1918).³

If we turn to the work of other early ornithologists we can track the northward creep of the Tufted Titmouse. Edward Howe Forbush somewhat hesitantly gives them an entry in the third volume of Birds of Massachusetts and other New England States (1929). He characterizes them as a "very rare or casual visitor," and a "mere straggler in New England." In those bad old days when ornithologists insisted on having a "taken" specimen in hand, rather than a mere "sight record" to establish a bird's residency in a given area, Forbush explains that he has "not listed it as a Massachusetts bird because although several sight records have been given me we have no record of a specimen taken in the state."

He confesses that he'd never had a good opportunity to observe Titmice himself, so we are not treated to any of the lovely descriptive prose that enriches so many of his first-hand species accounts. Rather, he relies on the words of others, from other states, to supply notes about nesting and feeding habits. But Forbush goes on to indulge in a bit of prognostication: "I predict that it will be taken and listed eventually in every New England state, as these states are not very far from its normal range and individuals are prone to wander more or less." (vol. 3, pp. 365-366)  He notes only one confirmed specimen from Maine, taken possibly in 1890, near Orono.

"Crested Titmouse," John James Audubon

Similarly, Mabel Osgood Wright, in the 1936 edition of Birdcraft, comments that "The Tufted Titmouse is quite rare here [i.e. southern Connecticut, where she lived], but is a summer, and perhaps, winter resident in southern New York." In the 1947 edition of Field Guide to the Birds, Roger Tory Peterson gives northern New Jersey as the northernmost limit of the Titmouse's range. By the time of his 1980 revision, he included a range map (Map #249) that indicated Titmice had moved northward to occupy territory through all of Massachusetts, as well as southern Vermont and New Hampshire, and had even crept into southern York County in Maine. In a note on the map Peterson says that the bird is "Expanding range north (helped by feeders)."

In a study published in 1999, Colby College ornithologist W. Herbert Wilson found that Titmice had begun to establish nesting and breeding populations in Maine as far north as Waterville. By now they are common in many parts of the state, though perhaps not yet in the far northern reaches. They are beginning to move across the Canadian border into the Maritimes, but are still considered rare in New Brunswick. A birding friend in Halifax rues the fact that they have not yet gotten across the Bay of Fundy to Nova Scotia.

Titmice are just one of several bird species that are now common around us but whose residence this far north is a relatively recent development. Seeing a Northern Cardinal at our farm in western Massachusetts was an exceedingly rare treat when I was growing up, much to my father's dismay; they were one of his favorite birds. Now a pair frequently visits our place in Maine, though they are not as omnipresent as some of the other species I mentioned.

I'd never even heard of, much less seen, a Red-bellied Woodpecker until I moved to Tennessee. They are another species that was regarded as an "accidental" in Forbush's day and was termed "casual" in New England by Arthur Cleveland Bent in his Life Histories of North American Woodpeckers (1939). They are also another species that Peterson, in his 1980 edition, noted was expanding its range north. Now we have a pair around much of the time. In the summer of 2015 I located a nesting site in our woods. Later on that year we were tickled to have a couple of young ones show up at the house in company with their parents. Maine Audubon naturalist Doug Hitchcox has written about the expansion of their range into Maine and presents data from eBird to show where they are now occurring in our state.

So what is behind this gradual, but persistent, northward movement of our friend the Tufted Titmouse, the Red-bellied Woodpecker, and other species? We have seen that this trend has been going on for quite some time--recall Forbush's prediction in 1929 that Titmice would eventually take up residence throughout New England, and Peterson's 1980 comments about backyard feeding contributing to range expansion. Most current commentators, however, point to global climate change as a major factor. Whether or not this has been at work since the early 20th century and is only now being recognized as a force is not something I'm qualified to comment on.

If this is the case, we should perhaps look at the presence of new species in our neck of the world as something of a silver lining in the cloud of man-made climate change. As I write, the thermometer reads 12° F and there's a nasty wind gusting. Numerous Tufted Titmice are busy at the feeder outside my office window, competing for food with a larger group of Chickadees. Whatever factors brought them here, I am delighted with their presence! I must go now and refill the feeders.

² Titmice are such a commonplace around the house that apparently I've never exerted myself to get any photos of them! In the absence of any original images I use as the lead illustration for this post the Titmouse card from the Seventh Series of  "Useful Birds of America," issued in 1918 by the Church & Dwight company, makers of Arm & Hammer and Church brand baking sodas. This was one of ten series of trade/trading cards issued by the firm over the course of many years. Numerous other companies issued similar series of cards as part of a movement to educate people about the importance of birds. The Church & Dwight cards carry the slogan "For the good of all, do not destroy the birds." These cards will be the subject of a future post, or perhaps multiple posts. The painting of the Titmouse was done by Mary Emily Eaton, a British artist who lived in the U.S. from 1911-1932, and who was better known for her botanical illustrations. She did all the paintings for the third, fourth, fifth, sixth, and seventh series for Church & Dwight..
