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.

June 28:

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.

June 15:

Most of the Bluebirds that have been nesting in Boothbay Region Land Trust nest boxes are now working on their second broods of the breeding season. All of the Tree Swallows on those same preserves are in the final phase of their single broods of the 2026 breeding season; and the only Black-capped Chickadee that established residence in a BRLT nest box this season will soon bid her youngsters farewell. Now, let’s take a closer look at these preserves.
Five young Bluebirds at Autumn View are expected to fledge in the next 24-48 hours, while eleven Tree Swallows from 2 nest boxes are not expected to fledge until later this month and the first week of July.
After four young Bluebirds fledged at Lobster Cove Meadow in late May, there has been no sign that a second nesting attempt has been made. If a second brood is attempted, it typically starts about two weeks after the first brood fledges. We will keep watching to see how this plays out. Six recently hatched Tree Swallows will spend the next 2-3 weeks preparing to fledge in early July.
The single Bluebird nest at Oak Point Farm is now well into its second brood with 5 eggs in the nest. The 3 Tree Swallow nests at Oak Point Farm currently contain a total of 16 fast-growing youngsters, which are expected to fledge within the next 1 to 2 weeks.
Two Tree Swallow nests at Zak Preserve contain 11 youngsters that should fledge within the next week. We expect a second brood of Bluebirds to start at Zak any day now.
Singing Meadows still reigns as the Land Trust Bluebird “factory” with 3 nests containing 17 eggs, all of which are second broods for the season. Those 3 nests fledged 14 young Bluebirds in their first broods. We are waiting to see if a fourth Bluebird nest will join that group. Meanwhile, 2 Tree Swallow nests at Singing Meadows currently contain 4 eggs each.
Penny Lake rounds out this week’s summary with a Bluebird nest containing its first egg. This is the second brood for this nest box this season. We anticipate that between 4 and 6 eggs will be deposited. A Tree Swallow nest contains 6 youngsters that are expected to fledge within a week. Finally, the hard-working Black-capped Chickadee that is raising 7 youngsters is expected to bid them a fond farewell when they fledge in about 5 days.
June 7:
Busy, busy, busy! This season’s bird “baby boom” on Boothbay Region Land Trust preserves continues at an active pace with eggs being incubated and/or hatching, youngsters fledging, and new nests being constructed for second broods.
Most of the Bluebird nests on Land Trust preserves have now fledged their first youngsters, and the adults have already started building new nests to accommodate their second broods. Evidence of this was observed during the recent Thursday morning bird walk at Oak Point Farm, when both adult Bluebirds were seen carrying nesting material to their nest box. A nest box inspection on Sunday revealed a completely new nest ready to accept Bluebird eggs any day.

At Autumn View Preserve, five Bluebird eggs have hatched along with eleven Tree Swallow eggs in two separate nest boxes.
Lobster Cove Meadow’s single active nest box contains six incubating Tree Swallow eggs, which are expected to hatch this week.
Penny Lake preserve has six newly-hatched Tree Swallows, while three of the seven Black-capped Chickadee eggs were hatching on Saturday. The other four Chickadee eggs probably hatched later that day.

Five young Bluebirds fledged at Zak preserve last week, and six Tree Swallow eggs hatched. It’s likely the adult Bluebirds will begin building a new nest for their second brood later this week.

Singing Meadows remains busy with four active nest boxes. Two of those nest boxes contain about 10-11 Tree Swallow eggs being incubated. One nest box has a new Bluebird nest under construction for a second brood, while another Bluebird nest box contains six (second brood) eggs being incubated. We expect those eggs to hatch this week.
May 31:
The annual Bluebird baby boom is off to a good start this season! A total of 22 Eastern Bluebird fledglings left their nests on six different Land Trust preserves during the week of May 25-31. Six Bluebird eggs at Singing Meadows are expected to add to this total in about two weeks. Within another week or so, the parents of those 22 youngsters will begin rebuilding their nests in preparation for a second nesting attempt.

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.

As mentioned previously, the spring bird migration has peaked, but we are still seeing lots of new birds moving into and through Maine. Current bird observations at Land Trust preserves are revealing species not seen in previous weeks. Forty (or more) different species can be seen in an hour during a walk at Singing Meadows and Oak Point Farm. Some of the newer birds being seen include at least 10 different species of Warblers, Barn Swallows and Chimney Swifts, Baltimore Orioles, Flycatchers, Indigo Buntings, and Vireos. It is a great time to get out there (with binoculars and the Merlin app on your smartphone) to see and hear a huge variety of birds.
May 22:
The annual spring migration appears to have reached its peak here in Lincoln County between Friday, 15 May, and Tuesday, 26 May, during which time well over 7 million birds passed over the county. Monday, 25 May, had the highest single-day total in that five day stretch, with over 3,400,000 birds detected. Of course, only a fraction of those birds stopped in the Boothbay area after flying most of the night from somewhere well south of Maine. Still, that’s a sizeable number of birds, many of which (41 species) were seen and heard during a field trip to Autumn View Preserve last Saturday.
Although the daily numbers are beginning to decline, the spring migration is far from over. More birds will be coming through by the end of the month before the migration is essentially complete. Morning is the best time to see and hear birds, and the earlier the better. Most of the migrants will have landed in trees and shrubs, or on the ground, to rest and feed after flying all night.
One of the most unusual, if not rare, birds to appear in Maine this season is the Little Blue Heron. As the name implies, this bird is smaller than the more commonly seen Great Blue Heron but is a much darker shade of blue—almost slate-colored. A Little Blue was seen at Oak Point Farm on Monday, 18 May, and again on Tuesday and Wednesday. Hopefully, it will stick around for the summer!

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.

May 12:
Many of the Bluebird eggs we reported on last week have hatched. As of today, we have 19 new baby Bluebirds in 6 different nests at Singing Meadows, Zak, Penny Lake, and Oak Point Farm. The four Bluebird eggs seen in a nest at Lobster Cove Meadow last week are expected to hatch within the next 24 hours. Unfortunately, five of the six eggs in a nest at Singing Meadows failed to hatch, possibly due to the chilly, wet weather we had during much of the incubation period.

Tree Swallows continue their preparations to nest in several nest boxes on all Land Trust preserves, but as of this week, have not deposited any eggs. That is expected to change with warmer weather on the way.

The spring migration continues to build to its peak in Maine by this weekend, with thousands of migrants being seen every day all across Maine. Highlights include Ruby-throated Hummingbirds and Baltimore Orioles right here in Boothbay, and Blue-gray Gnatcatchers, Northern Parula, Summer and Scarlet Tanagers, and eleven different Warbler varieties elsewhere in the state. If you haven’t done so already, be sure to put out your nectar feeders for the hummingbirds. The nectar mix is 4 parts water and one part granulated white sugar, and be sure to change it every 3 to 4 days. No red food coloring is necessary.
May 5:
The local bird nesting season is well underway. We have nests containing eggs on five of the six land trust preserves with nest boxes. As of today, Bluebirds lead the way with a total of 27 eggs in six different nests. Singing Meadows has three nest boxes containing 4, 5, and 6 eggs, respectively, all of which are expected to hatch on or about May 6th. Lobster Cove, Oak Point Farm, and Penny Lake have at least one nest box, each containing 4 eggs. Most of those are expected to hatch within a week.
Tree Swallows are just beginning to establish nests on each of the preserves, but as of yet have not deposited any eggs in those nests. That should change as the weather warms up, leading to an increase in the flying insects needed by the adults to feed themselves and their young.
The Spring bird migration is really ramping up here in Maine, where we are seeing a daily increase in the number of birds returning from their winter vacations down south. Many of those birds are making their way to breeding grounds not just in Maine but beyond into Canada and as far north as the Canadian Arctic.
Recent local sightings include Broad-winged Hawks, several Warbler species, including Pine, Yellow-rumped, Northern Parula, Yellow, and Common Yellow-throat, as well as both varieties of Kinglets. Chipping, Swamp, White-throated, and Savannah Sparrows are becoming more frequently seen and heard as well. A few of the sea ducks (Surf Scoter, Long-tailed, and Common Eider) that winter here in Maine are still hanging around in the harbor and along the coast before they head north to their breeding areas.
Peak migration in Maine will occur in the next couple of weeks, with millions of birds flying every night and settling in the morning to rest and feed before resuming their flights north. This will be a great time to get out on Boothbay Region Land Trust preserves to witness this incredible miracle of nature at its best.
April 19: 

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.
