June 2009 Central Mass Bird Sightings
Sightings are listed in reverse chronological order. The email address of birders submitting reports, as well as other Central Massachusetts birding info can be found via the Central Mass Bird Update homepage.
Like last week's effort, teams kept in touch via cell phones using a phone tree system. In this way, the entire group kept up with what species was already "Confirmed" and what species still needed to be found or more closely observed. Now that we have 2 blockbusting efforts under our belts, the feeing by all involved is that this is a fun and efficient way to survey a block. Though this technique is not as thorough as spending 20+ hours observing stretched over several months, blockbusting is still an amazingly successful strategy.
WARREN 9 is a very varied and productive block, with several ponds, some nice power-line cut-overs, and the western sections of WELLS STATE PARK . Today we managed 93 species in a morning's effort with 57 species CONFIRMED, 12 PROBABLE, and 24 POSSIBLE and 2 OBSERVED. Compare this to a total of 62 species found in Atlas 1.
Late last summer the beaver dam (which is not on MAS property) breached and the lake drained. The beaver never made an attempt to rebuild, thus the water level is not sufficient to support the rookery. GB herons will not nest where there is no water.I think the main reason is probably fear of predation.(racoons etc). They did arrive right on schedule this spring but quickly moved on. There is a Green heron apparently somewhere in the immediate vicinity because we see and hear it out in the swamp almost daily. In addition there have been several sightings of Am. Bittern although we have not heard them, so my guess is they were passers by. Of interest is the extensive mud flats that have been created and the sighting of some shorebird types that were not previously known here. There were 2 Pectoral sandpipers on May 2nd, a first for the sanctuary. A Solitary was present right thru Bird-a-thon and we have had reports of Greater yellowlegs. Killdeer are a constant presence, probably breeding somewhere out there. We will be watching for more of that activity as the fall migration gets under way.(report from Dick Knowlton).
The Blockbusters consisted of (see group photo on Sheila Carroll's blog): Dan Berard Sr; Dan Berard Jr,; Deb Berard; Kevin Bourinot; Sheila Carroll, Rebecca Ciborowski; Alex Dunn; Simon Hennin; Mark Lynch; Paul Meleski; Jane Moosbruker and Steve Sutton. We broke into 5 parties, began at 7AM and met for the compilation at noon. All parties had copies of the topo maps for the block and were assigned specific areas to work in. A previous morning scouting the block enabled us to generate a hit list, and knowledge of the habitat and birds in central Massachusetts allowed us to arrive at a pretty comprehensive target list of possible species. We stayed in constant contact via cell phones, using a phone tree system so all anyone had to do was to call 1 person every time a species was upgraded or "Confirmed". This system worked fairly well, though there were some dead areas in the block for phone reception.
In this one morning 93 species were recorded, versus 42 species in Atlas 1!!!!!. Of those: 52 were "Confirmed"; 14 "Probable" and 27 "Possible". Interesting species in the confirmed and probable category: Osprey (pair on nest just off Rt.84); Pileated Woodpecker; Great Crested Flycatcher (nest found); Blue-headed Vireo (local in this part of the County); Bank Swallow; Red-breasted Nuthatch (ditto); Veery; Hermit Thrush, Wood Thrush; Field Sparrow; Indigo Bunting; Purple Finch and Pine Siskin (fledged young w/ad). Confirmed warblers included: Blue-winged; Yellow; Black-Throated Blue; Yellow-rump; Black-throated Green; Pine; Prairie; Black and White; Redstart; Ovenbird; Louisiana Waterthrush; C. Yellowthroat. Other interesting species found included Turkey Vulture; Northern Goshawk (ad); Red-shouldered Hawk; E. Screech Owl (very local in this part of the County); several territorial Ruby-throated Hummingbirds; Willow and Least Flycatchers; Yellow-throated Vireo. Warblers included N. Parula (most likely just an odd singing bird and not a breeder); Magnolia; Blackburnian (several: very local in this part of the County); Worm-eating (possible breeder in good habitat); and Canada (several).
Over lunch everyone agreed Blockbusting was really a fun way to atlas, and
an effective way to survey a block. Because we were each assigned a small
area to bird, you stayed in one or just a few spots, or hiked, and spent
more time tracking species down to observe behavior. Because you knew if one
team already had confirmed a species, birding was much more directed. In
other words, you knew what species needed to be more closely observed. Also:
all prime birding spots were covered during the prime birding hours of the
early morning. And because we stayed in contact with each other, in many
ways blockbusting was even more fun than a CBC. Of course, some species like
pewees and Ovenbirds are difficult at this time of the year to Confirm
despite all the teams working on them.
