BLACKSTONE NATIONAL CORRIDOR MIGRATION MONITORING

 

 

 

5/20/06    5:30AM-9AM

 

This is the pilot year for this Corridor-wide monitoring project. Personally I believe a well-trained observer in the field can tell you much more about the nature of bird migration than you can learn with just mist nets. Migration is about behavior as well as species identification. Where are they heading? Were they feeding as they were moving? How much song was occurring? What about cross-species interaction? Were there mixed species flocks? Many birds move through at tree top level and can only be noted by an observer who can take in the full complexity of migration in any one area. Plus, the nice thing is that we only minimally interfere with the bird’s lives during migration and breeding season.

 

This year’s monitoring day occurred during a period of very little active migration. From north to south, east to west in the Corridor, monitors remarked that most of what they tallied were migrant breeders. On the X-cel sheet, I have highlighted in Yellow those species we know were migrating through. Obviously observed birds could have also included “migrating through” individuals of species that also breed in the monitoring areas. For instance, a number of tanagers may appear in spring in any one area, but only a few stay to breed. Some may move much further along, while others may simply find suitable breeding habitat in adjacent areas. Several teams witnessed behavior of birds competing for territories. Knowledge of the breeding birds of any of the monitoring areas is helpful in noting whether there was a “higher than typical” number of any species on the monitoring day. Because I have done several BBS of the Pulaski/George Washington SP area, I knew I was seeing/hearing larger numbers of a few species, more than will eventually remain to breed. These species in Yellow can give us a solid shorthand understanding about how migration was going on that day. And this year, it was pretty poor.

 

Very few empids were noted. There were no Olive-sided Flycatchers, which migrate throughout the Corridor spring and fall. Numbers of Peewee’s were still very low in the western and higher elevation sections of the Corridor, indicating that many (most?) would still be migrating in later (hopefully). Very few non-breeding thrushes (ex: Swainson’s) were noted too. Missing entirely were warbler species like Tennessee, Cape May, the Oporonis and most of the Wilsonia. There were no southerly overshoots like White-eyed Vireo or Hooded Warbler. Numbers of Blackpolls were miniscule and only 2 Bay-breasted was seen. The areas with the highest numbers of species and the greatest variety of birds were those spots that have a large number and variety of breeding species. Yet I know each location monitored can also be a migration “hot spot”. Just not that Saturday.

 

Nota bene: Watch for the small red tabs in the upper right corner of the X-cel cells. Rest your cursor on them and you will see some additional sightings notes.

 

We need more teams for next year to fan out through more sections of the Corridor, particularly in Rhode Island. I will contact ASRI well in advance of the project next year to see if I can recruit some skilled observers there. I would like someone in Cumberland, someone in Lincoln (Lincoln Woods or Lime Rock) and someone in North Smithfield (Fort Nature Reserve) at the very least. I also would hope you will all return to do the same spots you covered this year.

 

 

MONITORING ACCOUNTS

 

BILL RASKU, BRUCE DeGRAAF, JAY RASKU, IRIS VICENCIO-RASKU: Airport Hill, Leicester (including Sylvester Street). Habitat: extensive managed fields (airport) with large tract of mixed forest along a dirt road and a small reservoir.

WEATHER: Cloudy-sunny; light breeze from the west; temp: 46-56F.

HOWARD SHAINHEIT et al: Broad Meadow Brook, MAS, Worcester MA.

Migrant monitoring, Broad Meadow Brook, 5/20/06, 5:30-9 a.m.

Weather: Calm to breezy as the morning went along; sunny mostly w/ some light clouds late; 47  to 57 degrees.

We covered the 5 miles of sanctuary trails in 3 teams of 2 each.  Birders: Howard Shainheit, John Shea, Brian Mulhearn, Sheryl Farnam, Kevin Bourinot, Rebecca Ciborowski.  (The latter two are taking John Liller's class; Kevin helped us on Birdathon.)

Habitat is very mixed: upland deciduous wooded areas (very little pines); power lines; open, grassy areas, small marsh etc. All of it in an urban setting.

Overall, there was considerable song and breeding behavior, but very few obvious migrants.  There was nothing approaching a wave or even anything that suggested movement.  Specific notes are below.


Nota bene: Howard’s group had so many notes, that I have included again their whole list. I have highlighted in yellow the species that are definitely migrants, as opposed to migrant breeders. As you can see, very little active migration was going on.

James Toledano, Cynthia Robertson, Tom Dodd: Upton SF.

HABITAT: Mixed upland forest and wetland; dirt roads and hiking trails through upland forest; two small ponds.

WEATHER: 45-57 degrees F; clear, no wind except for few small gusts from 5- mph SW.

DISTANCE: 4 miles on foot.

DISCUSSION: Mostly breeding species including great looks at breeding Blue Headed Vireos, but no definitive movement of any species seen. Species seen soon after 9:00, Black and White, Cardinal, Redstart, and Tree Swallow. No waves or even a white-cap.

 

JOHN LILLER/TOM SAYERS: Plummer’s Landing; Lookout Rock; Riverbend Farm: Northbridge/Uxbridge MA. Key areas of riparian forest right along the Blackstone.

 

Plummer's Landing (5:30-7:15), Lookout Rock (7:20-7:45), River Bend Farm (7:55-9:00)

Weather: Sunny to partly cloudy, winds calm to breezy from the south, 48-63 degrees.

We (Tom Sayers and I) walked in at Plummer's Landing to the field, which is gradually being taken over through succession.  We then walked up to Lookout Rock.  We finished by walking around the field at River Bend Farm.  (I have no idea about distances.)

Habitat: mainly wooded areas, both deciduous and mixed, along moving water; overgrown field: grassy field and managed field adjacent to it.  Water levels high but not flood stage.

There was a lot of song and breeding behavior, but we had virtually no migrants, and no clear movement.

Dan & Deb Berard:Douglas State Park, Douglas, Ma.

 

Habitat:Mixed forest with small stands of hemlock: with a large fresh water lake:some small marsh areas and cedar swamp areas.

 

Weather: 50-52 degrees F, partly cloudy, winds WSW 5-10 mph.

 

Distance: 10 miles by car a few stops along the perimeter mostly and about 4 miles walked on well marked trails.

 

Discussion: Most of our birds were breeding birds on territory. We saw a great courtship behavior between 2 Great-crested flycatchers. We had a large number of Veery of which some were scattered along the lawn in the picnic area so believe they may have been just moving through. In the picnic area there was also a flock of Canada Geese probably a non-migratory group since it seems too late for their migration. At our first am stop we had 2 Northern Saw-whet Owls calling to each other and then a few miles away we had 2 Barred Owls being chased by Crows. Black-throated Blue and Black-throated Green were very vocal and Ovenbirds were everywhere. There was a fishing derby from the boat ramp and the boats had motors 150-225 horsepower so there was very little on the water. Non-bids: several painted turtles.

 



 

MARK LYNCH/SHEILA CARROLL: Pulaski SF/George Washington SP, Burrillville/Glocester RI.

HABITAT: Mixed upland forest; a few small stands of hemlock; dirt roads (of varying condition) through the forest; an area of power lines; some small ponds.

WEATHER: 46-56 degrees F; partly cloudy; cool; winds: WSW: breezy, measured to 10+mph; For the most part we were protected among the trees.

DISTANCE: 13.1 miles by car, many stops and several short hikes. A standard point-count route we do of the area.

DISCUSSION: Mostly breeding species though higher than typical breeding numbers of BT Green and Northern Waterthrush. The few non-breeding migrants we had (Blackpoll, Bay-breasted, Parula) seemed to be moving rapidly through the forest in a WSW direction. Which seems very odd for spring migration. Within ten minutes after ending the count at 9AM, and still “on site”, we had 4 species that would have been new to the list: Barn Swallow, Blue-gray Gnatcatcher, American Redstart, and Indigo Bunting (all breeders). We witnessed several (c.5) pairs of male Scarlet Tanagers chasing each other. Another sighting was of 3 male Black-throated Green Warblers chasing each other, NONE of them singing. A female Pine Warbler was seen foraging on the ground. This bird was so territorial; it made a pass at Sheila who had gotten too close. NON-BIRDS: (2) White-tailed Deer; a few cold Peepers.
