MAPS Visit 2, June 20,2007

Gray Catbird (Seabrooke Leckie-TTPBRS)

The second MAPS visit of the summer got underway on the cool morning of June 20th. It was the slowest day of MAPS banding we have had to date and yet lots of activity was present during the morning. There were at least three Wood Thrush territories identified within the study area and as many as 5 singing American Redstarts. A singing Ovenbird was a first for the project and singing Horned Lark, Purple Finch and Indigo Buntings were also noteworthy. A total of 53 species were recorded on the day, which is considerably higher than the 39 posted on the same day in 2006.

MAPS Visit 1, June 10, 2007

Wood Thrush (TRCA-Seabrooke Leckie)

The second year of the Monitoring Avian Productivity and Survivorship (MAPS) program at Claireville Conservation Area got underway on June 10. The MAPS program is a continental initiative to monitor vital rates (productivity and survivorship) of breeding landbirds. Calculations of vital rates are then used to determine the causes of population trends at local, regional and continental scales. Our site at Claireville is one of just a handful in Ontario and we are excited to learn about the demographics of local bird populations in relation to urban conditions and as a means of measuring habitat quality.

We were hoping to see returning Wood Thrushes, American Redstarts and Rose-breasted Grosbeaks and we were not disappointed. A total of 37 birds were captured and activity in the area was high with great diversity including Black-billed and Yellow-billed Cuckoo, Scarlet Tanager, Orchard Oriole and Northern Mockingbird. On the first visit a year ago we captured 50 birds, so the nets were less productive this year but it seemed that there were more birds around. We will be back for visit 2 next week.

Ebony Jewelwings are very common along the meandering rivers and creeks (TRCA-Seabrooke Leckie).

This is the first Savannah Sparrow we have banded during MAPS at Claireville. The species is very common in the surrounding grasslands along with Bobolinks. Upland Sandpiper, Clay-colored Sparrow and Grasshopper sparrow are uncommon breeders in the meadows (TRCA-Seabrooke Leckie) .

Migration Monitoring at TTPBRS- May 27-June 2

Mourning Warbler (TRCA-TTPBRS)

Following the hustle and bustle of mid-May, migration has been steadily winding down. The flycatchers, vireos and thrushes of late spring have been less abundant this year than in years past, perhaps owing to ideal conditions for nocturnal passage. Despite low numbers of migrants, the study area has been a very active place for birds with impressive numbers of nesting birds. On May 26, the explosive song of our third Connecticut Warbler of the spring was heard. Swainson's Thrush was the most common migrant recorded, followed by a smattering of flycatchers and warblers. Showers dampened the dry foliage at TTPBRS on May 27, when the 2nd station record of Orchard Oriole was spotted. Numbers of migrants picked up on the 28th as 61 birds were banded, and a late surge of Magnolia, Blackburnian and Black-throated Green Warblers was noted. The National Post visited the station for a feature story on this day. Marisol Ayala, a Masters student in the Environmental Studies Program at York University, spent the morning filming our work on the 29th. Marisol is working on an educational program to teach Costa Ricans about migratory bird conservation. The capture of two Silver-haired Bats on May 31st was unusual. The secretive Gray-cheeked Thrushes were well sampled by the nets this day as 14 were banded. South winds and high temperatures continued on June 1, with 32 birds banded, including the season's first Yellow-billed Cuckoo. Several Ruby-throated Hummingbirds, a total of 5 Mourning Warblers, and a very late Ruby-crowned Kinglet were standouts on an otherwise quiet June 2nd. The Spring 2007 Migration Monitoring Program will finish on Friday, June 8.
