2015 Bradbury Mountain Hawkwatch Season in Review

1 Reply

The 2015 Bradbury Mountain Spring Hawkwatch, co-sponsored by Freeport Wild Bird Supply and Leica Sport Optics, came to its conclusion on May 15th. This season was an interesting one, especially in how the weather affected our counts. During the 2-month period, the Official Hawkcounter, Andrew Wolfgang, tallied a total of 3628 raptors. This included vultures, hawks, eagles, and falcons. Over the 8-year span that we have conducted this standardized count, this year was the second lowest, coming in 12% below average.

Welcome to spring hawkwatching in Maine, Andrew!

However, a single year’s count tells us little beyond what the weather conditions were like during the course of the season. The late arrival of spring was actually a benefit to the count at the start, as few early migrants had progressed north by March 15th. Therefore, we had very good counts of our earliest migrants: Bald Eagles, Red-shouldered Hawks, and Turkey Vultures. In fact, we set a new record for eagles deemed migrating, and vultures produced our second highest tally of all time. We simply didn’t “miss” any of these migrants before the project got underway.

Bald Eagles set a new all-time record this season.

However, as the season progressed, spring still didn’t seem to arrive. Lots of unfavorable (for viewing birds at Bradbury Mountain) winds meant that viewing migrating hawks past this mountain was not optimal. Strong and cold west winds, for example, push birds towards the coast beyond our view, while persistent easterlies seem to shunt birds inland before they reach the northern terminus of the coastal plain. Simply put, the poor conditions during the peak of our migration period in mid to late April really lowered the overall numbers and it’s those couple of weeks that can really make or break the overall count for the season. Therefore, the below-average numbers of our two most abundant migrants (Broad-winged Hawk and Sharp-shinned Hawk) combined to yield a below-average season total.

However, we had some great birds once again, highlight by our 4th record of a Golden Eagle.

Andrew also recorded a new record of 3 Rough-legged Hawks, no doubt due to the late onset of the spring’s flight (most Rough-legs probably move north before the start of the count in most years).

Meanwhile, a total of 85 species were recorded, including an ever-increasing number of Sandhill Cranes. This year a total of 11 migrant cranes were recorded. Other highlights included frequent visits by Bohemian Waxwings to the summit for much of the first half of the count, both Red and White-winged Crossbills. Fox Sparrow was recorded at the summit for the first time as well (two dates).

But, this hawkwatch is not just about the numbers. We also work hard to educate visitors to the park, both birders and non-birders. Every year we expose more and more people to the world of hawkwatching and bird migration in general. Bradbury Mountain is just one of many hawk migration sites throughout the continent. The data we collect becomes part of this vast network allowing researchers to determine population and geographical trends in particular species. So, even though our numbers this year were low relative to past seasons, it becomes no small part of building this data set. 1174 visitors were recorded at the hawkwatch (tabulated as coming specifically for the hawkwatch or spending time chatting with the counter), plus many hundreds more who at least briefly read the sign or asked a question or two. This was slightly below average, but likely due to the cool conditions for most of the season.

There are few public projects where scientific data collection so effectively goes hand-in-hand with public outreach and education. With the growth of regular hawkwatch visitor volunteers, and especially the growth of the “Feather Over Freeport: A Birdwatching Weekend” festival, we look forward to many more years of introducing people to hawkwatching and hawk research and conservation.

Peregrine Falcons just eclipsed our annual average this year; most migrants in this area stick closer to the coast.

Our ninth Spring Hawkwatch kicks off again on March 15th, 2016! We invite everyone, whether seasoned veteran hawkwatchers or casual nature enthusiast, to join our professional biologist and naturalist at the summit once again.

It was quite a change in climate and the color of the scenery since the start of the count!

Monhegan Island, May 18-20, 2015.

Hooded Warbler, Yellow-crowned Night-Heron, Summer Tanager, Grasshopper Sparrow, 19 species of warblers and 89 species? All in 48 hours? It must be Monhegan!

Jeannette and I escaped for a quick trip to Monhegan Island this week. It was all-too-brief as usual, but we’re always happy for whatever short visit we can muster. With the early season ferry schedule still in effect, we couldn’t arrive until noon on Monday, and departed at 12:30 on Wednesday. That only gave us 48 hours of birding.

IMG_1020_edited-2
Northern Parulas were common and conspicuous – and looking mighty fine! – throughout the visit.

A strong flight overnight Sunday into Monday ushered in some new migrants to the island, but also ushered out several of the rarities that had been present over the weekend. Luckily, a few goodies lingered, including the adult Yellow-crowned Night-Heron that was seen almost all day for all three days of our visit in a corner of the Ice Pond. Our best discovery of the trip was a Grasshopper Sparrow that we kicked up near the microwave tower. Unfortunately, it was not seen again by us or anyone else.

The remnants of the good morning were present – it was decidedly birdy and we managed 16 species of warblers and 65 total species of birds before dinner…and with the pleasant surprise of finding Monhegan Brewing open, we may have spent a little afternoon time there instead of beating the bush.

Magnolia Warbler was our most common warbler on Day 1.

Come nightfall, birds took the air on light southerly winds. However, after midnight, there were very few
birds on the radar near the coast, suggesting many more birds would have departed than arrived. And that certainly was the case!

It was a quiet morning, and in the dense fog, birds were few and far between. The Yellow-crowned Night-Heron was present and accounted for however. Then, in the afternoon, Jeannette and I (mostly) circumnavigated the island – a hike I haven’t done in a while, so that was a nice change of pace. The only Cape May Warbler we saw in the three days was during the hike, in one of quite a few small mixed-species foraging flocks that we encountered on the island’s east side.

We also came upon a tired and wet Scarlet Tanager (I can’t believe I didn’t bring mealworms on this trip!), which was slowly working the rocks for seaweed flies. It was finding several, and after watching it for about 15 minutes, we can tell it was getting a little more strength.

Upon our return to town, we were alerted to the re-sighting of the weekend’s Summer Tanager, flycatching on Swim Beach. To say it posed for pictures would be an understatement.

Overall, it was a slow day of birding by Monhegan standards (55 species including 13 species of warblers), but a slow day of birding on Monhegan is a great day of birding most anywhere else!

Although we awoke to more dense fog on Wednesday (5/20), our last day on the island, there were soon peaks of sun overhead, and a lot of new birds were to be seen. A moderate flight overnight on light southwest winds then saw birds drift offshore a little more as the winds shifted to the west after midnight. This brought an array of new arrivals to the island, although nothing in exceptionally large quantities, but our trip list grew steadily.

Our morning began with a nice flight of Northern Gannets off Lobster Cove and ended with 17 total species of warblers. Personal first-of-years included the gannets, 1 American Pipit at Lobster Cove, and a singing Willow Flycatcher.  The Summer Tanager continued, and the Yellow-crowned Night-Heron was still standing guard.

And finally, we ran into the one rarity that we had not yet caught up with – a female Hooded Warbler that had been present since the weekend. In true MonhegZen birding style, after being told we “just missed it” several times, I played a hunch and gave one little thicket a quick check before we headed up to the Trailing Yew to grab our carry-on bags.

And sure enough, there she was!
IMG_1180_edited-2

While both a Wood Thrush and Snowy Egret that were seen on Tuesday would have been “Island Birds” for me, we managed to see all of three of the continuing rarities, plus finding our own in the Grasshopper Sparrow (a very good bird out here).

In other words, it was a great – albeit quick – trip. I look forward to returning no later than our MonhegZen Fall Migration Weekend, if not sooner.  And for the record, Monhegan Brewing’s new Flyway IPA – named for the birds and birders that descend on the island each spring and fall – is fantastic!

But most conspicuous in their complete absences was the lack of Carolina Wrens. The island usually has the densest population of this “southern” species anywhere in the state (although one neighborhood in Wells might rival it), but we did not have a single bird the entire trip! Same for everyone else we talked to. Apparently, the unusually harsh, long, and snowy (especially for out here) winter took its toll – as it is wont to do on Carolina Wrens pushing the northern limits of their range.

Chestnut-sided Warblers were one of many species that were more frequently encountered this morning that in the previous two days.

Birding and Conserving Sandy Point and Knight’s Pond-Blueberry Hill

Leave a reply

Warbler migration is in full swing right now, with at least 10 or more species easily found on most mornings at most productive patches. Nonetheless, I really hate to say it, but in less than 3 months, some of these birds will already be returning home to the Neotropics. In fact, in a little more than three months, I’ll be back at “my office” at the base of the bridge at Sandy Point on Yarmouth’s Cousin’s Island to count southbound migrants!

It’s true: the birds we think of as “our” birds that spend the winters in the tropics are actually tropical birds that spend a few months of the year taking advantage of the bounty of insects in the northern forests in the short summer. While it may feel like fall today (after yesterday’s 80-degre temps!), I only bring this up because the Morning Flight at Sandy Point was on my mind this morning, as I met with Central Maine Power and Lucas Tree.

As many of you will remember from the fall of 2011, enhanced maintenance (Federally required) of the high-tension powerline corridor through Sandy Point significantly impacted the most critical migratory bird habitat here. With the help of many of you also calling CMP and sending letters, the clear-cutting was stopped, but much to my chagrin, was resumed in the spring of 2012 without notice. To make a long story short, after several months, an agreement was reached. The agreement and essentially an apology from CMP has been posted on our website ever since.

The trees were planted, and the River Birch is doing well. While the Red Oak didn’t make it through last summer, a cherry has naturally resprouted nearby and is currently outperforming the other trees at the base of the bridge – the most critical trees for reorienting migrants. These trees are outside of the critical clearance area under the lines (one of my biggest arguments in the first place) and will continue to grow (excuse the pun) in importance to birds seeking shelter or rest before making the crossing to the mainland.Sandy Point1,5-8-15

An early spring view from “My Office.”

Knowing that Sandy Point was due for the three-year maintenance schedule, I sent a email to CMP this winter, just to check in. I was assured that someone would be in touch this year when this stretch of corridor was due to be cut. And sure enough, last week, Nicholas Hahn of the Vegetation Management division of CMP got in touch, and I met with him and a crew from Lucas Tree this morning to discuss the current cutting regime.

First, let me say that I am very happy that CMP honored their commitment to notifying me about upcoming maintenance, and I greatly appreciate the opportunity to offer input. We all agree it’s easier to get on the same page before any work is done. I’m not unreasonable, and I don’t need to get upset any more than I have to.

We walked through the site and the trees that needed to be removed or pruned (fast-growing trees that could get too tall before the next scheduled maintenance in three years, aka “capable”) were identified. It all seemed very reasonable to me, and I had no objections. I did make sure the cutting of the Staghorn Sumac patch was kept to a minimum, and Lucas Tree agreed to take out a few bush honeysuckles before they got any bigger and further impacted the valuable Arrowwood Viburnum stands.SandyPoint2,5-8-15

So all in all, it went very well, in my opinion. There wasn’t much that needed to be done, and this small stretch of corridor will continue to be maintained with the lightest hand possible, offering safety and refuge for tired birds, and exceptional opportunities for us birders.

After the meeting, I finally got over to the Knight’s Pond – Blueberry Hill property on the Cumberland/North Yarmouth border that the Royal River Conservation Trust and other organizations have been diligently working to preserve. It’s only my affinities for my local patches at this time of year that has kept me from checking out the preserve sooner.  But I am glad I finally did.

It was already 8:20am by the time I arrived, and therefore the sunny edges were less busy. And since the deeper woods are not yet too active, the overall birding was a little slow today. However, there’s clearly a lot of potential for birding opportunities here.

KnightsPond1,5-8-15

10 species of warblers were present this morning, including my first Chestnut-sided and, in the powerline corridor, my first Prairie of the season. My “FOY” Great Crested Flycatcher sounded off, and I was rather surprised to encounter a Black-crowned Night-Heron, a state Threatened (and proposed for upgrading to Endangered species). The pond is big enough to be worth a check in waterfowl migration, and I bet it can host a lot of swallows in early spring.  And there’s likely a lot more breeding around its edges and deeper in the woods than what I detected this (still) early spring day.

In other words, I will be back, and don’t be surprised to end up here on a future Saturday Morning Birdwalk. This property is a great addition to our local birding patches. Unfortunately, politics has put the purchase at risk. This is one of 30 projects at risk thanks to the Governor’s refusal to release voter-approved bond money for the Lands For Maine’s Future Program.

Voter-approved bonds are not political bargaining chips. These have been approved by voters and are not subject to the Governor’s personal approval – he’s not a king, although sometime he tries to act like it. The protection of Knight’s Pond has no relation at all to increased timber harvesting on state land (don’t get me started on that one…deer yard “thinning” anyone?). Hey, I get politics – things are negotiated and compromised. In theory. But as usual, with this “Governor,” it’s not about compromise – it’s about getting his way.

We all know how kids change the rules of the game when they’re not winning. I probably did, and you probably did too. And every neighborhood had that kid who, upon not getting his way, took his ball and went home. To me, this is akin to what the Governor is attempting to do – except this is not a child’s playground. There’s a reason it’s called the “Land for Maine’s Future” program. And the time is now for the Governor to grow up, act like a Governor and not a spoiled child, and release these bonds so this property and other valuable parcels can be conserved for all Mainers – forever – before it’s too late.
