Carlisle Spring Bird Walk
An overflow crowd of 35 early risers turned out for the 28th annual conservation commission Spring Bird Walk on the Towle Conservation Land Sunday, May 16. With cool, dry weather in the first half of May, migration appeared to be somewhat retarded. Warblers and many other usual migrants were in short supply, but so were mosquitoes.
Highlight of the walk was a Louisiana Water-thrush, first heard singing from the main loop trail in the southern part of the woods, then later well-seen further north from the same trail. This warbler, which inhabits woodland swamps, is at the northern limit of its range in Massachusetts and is always a good "find." The last observation on the Spring Bird Walk was in 1994, when it was heard in the same area but could not be seen.
Altogether, 42 species were seen or heard, one more than last year. These included a Great Blue Heron, a pair of Red-tailed Hawks, four Great Crested Flycatchers, four Brown Creepers, including one at a nest under bark on a dead white pine, two heard-only Winter Wrens, three thrush species singing (Wood Thrush, Hermit Thrush, and Veery), a pair of Eastern Bluebirds, a Warbling Vireo heard, three Blue-winged Warblers, and nine Baltimore Orioles. Five male Bobolinks were counted in the main field, up from three last year. The conservation commission's policy of not mowing in the summer is working well!
