Volunteer and long-time birder, Stan Wakefield, shares regular updates and pictures on bird nesting activity at BRLT’s bird boxes monitored at Oak Point Farm, Singing Meadows, Lobster Cove Meadow, Penny Lake, and Zak preserves. Data is also reported to NestWatch, a citizen-science monitoring program developed by the Cornell Lab of Ornithology and used nationwide to track the status and trends in the reproductive biology of birds. We encourage readers to check back frequently from April-August to keep up on all of the changes throughout the season.
——————————————————————————————————————-
With the onset of true summer weather, the observable bird breeding season on six Land Trust preserves has reached the halfway point. On three of six preserves, the Tree Swallows have finished their single-brood season with 33 new, young Tree Swallows having fledged and now chasing flying insects. The last group of 17 young Tree Swallows is expected to fledge by the first week of July. The Bluebird nesting season continues with second broods on at least three preserves.
As expected, five young Bluebirds fledged at Autumn View Preserve in mid-June. Eleven young Tree Swallows from two nest sites have fledged, or will have fledged, by the first week of July.
There is no sign of a second nesting effort by Bluebirds at Lobster Cove Meadow yet. The six young Tree Swallows at Lobster Cove are expected to fledge in early July.
Sixteen young Tree Swallows from 3 nest sites have fledged at Oak Point Farm since 15 June, leaving one active Bluebird nest containing five recently-hatched youngsters.

Five Bluebird eggs, marking a second brood, have been deposited in a nest at Penny Lake since June 15th, while six young Tree Swallows and seven young Black-capped Chickadees fledged on June 18th and 24th, respectively.

Eleven young Tree Swallows are believed to have fledged at Zak Preserve last week, with no sign yet of a second Bluebird nesting effort.

Finally, Singing Meadows remains active with two nest sites containing eleven (second brood) Bluebird eggs. Four young Bluebirds are believed to have fledged today (28 June), while four young Tree Swallows are expected to fledge within the next two days.

Tree Swallows currently nesting on six Land Trust preserves may break a record for the number of youngsters raised this year. So far at least 59 eggs have been deposited in eleven nest boxes, with several more expected to be seen. None of these eggs have hatched yet, since Tree Swallows start nesting a few weeks after the Bluebirds. When they do hatch, there’s likely to be something of a bird traffic jam in the skies over the Boothbay peninsula!

Closing out the nesting bird news is a nest box at Penny Lake that is hosting a Black-capped Chickadee. This is not unusual, but it also does not occur every year. There are seven eggs in the nest, and we hope all will hatch, grow, and fledge successfully.

We have seen no activity on the Osprey nest platform at Oak Point yet, but there still might be time for a pair of “Seahawks” to take up residence and start building a nest. If it doesn’t happen this year, we believe it will occur in 2027.

Bird breeding activity in the Boothbay area is picking up with Tree Swallows starting to lay eggs in nests on several BRLT preserves. Autumn View currently has 9 Tree Swallow eggs in 2 different nests and 4 Easter Bluebird eggs in another nest. There are 4 growing young Bluebirds at Lobster Cove Meadow and 4 more young Bluebirds at Oak Point Farm. Tree Swallows are not to be outdone at Oak Point, boasting 9 new eggs in 2 different nests. Penny Lake is doing well with 4 young Bluebirds in 1 nest and at least 3 Tree Swallow eggs in another. Singing Meadows still leads with 9 young Bluebirds in 2 different nests. And finally, Zak is doing well with 3 young growing Bluebirds and 6 new Tree Swallow eggs.

The Osprey nest platform at Oak Point hosted the first reported visit of an Osprey on Wednesday, 20 May. It’s too soon to say if there will be repeated visits.

The Kestrel nest box at Zak Preserve, which is being monitored by Midcoast Audubon, had a few brief visits by a male Kestrel last week, but no evidence of nesting activity has been identified since that time.

Despite some cooler-than-usual weather, spring bird breeding activity is off to a good start on the Boothbay peninsula. Eastern Bluebirds have not only started building nests on most of our land trust preserves, but they also have already laid eggs in at least four of those nests. Singing Meadows is currently in the lead with four nests, one of which already has four eggs. Eggs are anticipated in the other three nests in the near term.

So far, Oak Point Farm and Penny Lake Preserves each have one Bluebird egg each in a nest, with more anticipated this week.
Lobster Cove Meadow and Zak preserves have one nest each with Bluebird eggs expected soon. Autumn View has Bluebirds and Tree Swallows hanging around, and nests with eggs are anticipated there as well.
The spring bird migration is well underway, as exemplified by the birdsong that is easily heard on the preserves. By far, the most vocal birds you are likely to hear during a walk on the trails include Song Sparrows, Goldfinches, Robins, Red-winged Blackbirds, Titmice, Black-capped Chickadees, and Cardinals. Many other bird species will be arriving daily, adding their songs to the avian symphony.
For those of you who like to walk at Oak Point Farm, you will likely see a new bird-related “structure” on the property. An Osprey nest platform was recently installed to the right of the trail from the farmhouse to the dock. We are hopeful that a pair of Ospreys will soon find the platform to their liking and build a nest on it this season.
