Saturday, September 25-2004

Highlight of the banding today was the capture of 2 Cape May Warblers, the only "Capes" banded this fall.
A single Red-headed Woodpecker and American Golden-Plover were sighted at the research station today. Both sightings are just the second records of each species at TTPBRS.
Also seen today were about 700 Blue Jays along with many Monarchs moving southwest over the park.

Migration Monitoring at TTP-September 16-22

A busy week.....

As anticipated, north winds and cooler temperatures brought more birds into Tommy Thompson Park, especially thrushes and the first of several late fall species. This weather pattern led to 97 birds being banded on the 18th and 95 banded on the 19th. Grey-cheeked and Swainson's Thrush along with Nashville and Black-throated Green Warbler were the dominant species on both days. The migration of Grey-cheeked Thrushes has been particularly impressive in fall 2004 as over 50 have been banded so far (compared to a total of 23 last year). A remarkable tally of 70 species was recorded on the 18th making this the highest one-day species total for fall monitoring at TTP (52 was highest in 2003 on September 26).

Weather for next week looks favourable for more excellent birding and banding at Tommy Thompson Park!

Migration Monitoring at TTP-September 9-15

Still quiet.....
Migrant landbirds were hard to find during the update period as persistent south winds and clear conditions limited the possibility of a "fallout" in southern Ontario. Warblers, vireos and thrushes are still coming through although the bulk of them are likely passing us by in the dead of night! Noticeable by their absence are Blue Jays in fall 2004. On September 16, 2003, 1700 were counted at TTPBRS. As of September 15, 2004, only a few had been counted. Similarly, we have yet to see many Monarch Butterflies passing over the banding lab on peninsula D. Otherwise, we are pretty much at par with results from last fall, due in part to a lack of northern cold fronts in both years during August and September.
A shift in the weather is forecasted for the next few days so maybe the wait is over!
Ps. 13 Sandhill Crane were spotted flying south during census today. This sighting constitutes the first record of this species for TTPBRS.

Migration Monitoring at TTP-September 2-8

South winds=empty nets.....
We are in the midst of a September lull as unfavourable south and easterly winds have kept landbird numbers down at Tommy Thompson Park. Banding totals averaged about 12 birds banded per day for the first week of September! Landbird migration has been rather weak thus far for all of southern Ontario. One would expect that the bulk of the warblers and thrushes will make things a little busier in the coming days and weeks.
Despite the near absence of birds the past week, 53 park visitors were treated to banding demonstrations at TTPBRS on labour day weekend. We were fortunate to have a few interesting birds to show them! Education is the most important directive of our activities at the research station and we are looking forward to the students coming in late September and October.

Tommy Thompson Park Bird Research Station

The Tommy Thompson Park Bird Research Station (TTPBRS) was established in 2003 by Toronto and Region Conservation in 2003 and is dedicated to the understanding, protection and awareness of birds in Toronto.


ory Birds

Many migratory bird populations are declining because of habitat loss at nesting, migrating and over-wintering sites. To protect these species, we need to monitor them. Canada’s northern boreal forests are vital to migratory bird populations of North and South America. However, these remote forests are mostly inaccessible to Breeding Bird Surveys. This problem led to migration monitoring as a way to keep tabs on the health of birds in the north. At TTPBRS, birds are counted daily during spring and fall migration through bird banding and surveys. In addition to the core Migration Monitoring Program, TTPBRS also conducts a monitoring program for migratory owls.

Breeding Birds

TTPBRS monitors breeding birds every year throughout the Greater Toronto Area (GTA). The impacts of urbanization on nesting birds in the GTA are a specific focus of our breeding bird monitoring efforts. Data from these programs help conservation agencies protect birds and their environments at local, national and international levels.


ological research is another main objective of the station. We provide opportunities for students and professional researchers to study birds and to develop their skills. Staff and volunteers participate every year in various projects with researchers.


The clo
se proximity of the research station to a major city affords us a unique opportunity to engage a large population at a site of global significance for birds. Education programs for students and the general public are a focus of the research station. Our curriculum based program, Winged Migration, is offered to grades 4, 6 and 7. Staff and volunteers also provide regular demonstrations for visitors and training opportunities for those interested in the study of birds.


Migration Monitoring at TTP-August 26-September 1

Here come the warblers...
Birding has improved at Tommy Thompson during the past week as warblers have started to come through in high numbers. The north winds that dominated the latter half of the week produced some migrant "waves" at TTPBRS. Unfortunately, most of the birds are favouring the cottonwood and birch canopy to the lower dogwood and willow where the nets are! A season high 39 species were counted on census on August 28 and yet we only managed to band 6 birds.
Banding totals during the past week ranged from 1 on August 27 to 47 on September 1. Strong north winds in the fall tend to push migrants out onto the TTP landmass, while south, east and westerly winds tend to keep migrants to the greenspaces on the Toronto lakeshore. Let's hope for some strong northern weather in the coming weeks!

Migration Monitoring at TTP - August 19-25

The drought continues....
Bird numbers remained low at Tommy Thompson for the third week of fall coverage, which is typical for mid-late August. The peak for Waxwings, Catbirds, and Yellow Warblers has now passed and we are now awaiting more northerly breeding songbirds. Warblers are just starting to show up in southern Ontario and we are hoping for a better showing for most warbler species this fall. However, recent reports of poor breeding conditions for boreal and arctic breeding birds may be reflected in our banding and census totals at TTP this fall.
Time will tell....

Migration Monitoring at TTP-August 12-18

Hello all,
The second week of fall migration monitoring was quiet for the most part. There were some interesting records however (see below). Numbers of Baltimore Orioles, Eastern Kingbirds, Traill's and Least Flycatchers have increased. The week also featured a host of newly arrived species from more northern breeding areas. The overall diversity of birds has been increasing by the day. Looking forward to the coming weeks of Blue Jays, Blackpolls and Sharp-shins!
We could still use some skilled birders for census and point counts at the research station. If interested please contact me!

Migration Monitoring at TTP-August 5-11

Weekly update on Migration Monitoring Results from Tommy Thompson Park for the week of August 5-11.
The first official day of monitoring for fall 2004 was August 5th. Typically, August has a slower pace than September and October although this migration "window" is critical for some species such as Yellow Warblers, Catbirds, Swallows and empidonax flycatchers. There has been a reasonable supply of these species during the first week, although banding totals are rather modest as is expected for this time of year. A few of the highlights are presented below.
1-Northern Waterthrush on August 5
12-Yellow Warbler on August 5
1-White-throated Sparrow on August 6
1-Canada Warbler on August 7
2-Nashville Warbler on August 7 (early)
1-Swainson's Thrush on August 7
1-Peregrine Falcon on August 5
1-Black-billed Cuckoo on August 5
1-Eastern Bluebird on August 7 (rare for TTP)
