Migration Monitoring at TTP-April 22-28

Still waiting.....
 
Only 46 birds were banded during the update period which is extremely slow for this time of year. Migration Monitoring stations across southern Ontario have had similar numbers for the week. Perhaps the birds are holding further south and just need a warm front to get them going! Species diversity has been lower than a year ago as only a few new arrivals were detected over the past week. Numbers of Myrtle Warbler have been gradually increasing although the major movements of this species as well as Ruby-crowned Kinglet and White-throated Sparrow are expected very soon. There were some unusual sightings since my last synopsis, the most notable of which was a flyover Dickcissel recorded on April 22! This was a first record for the bird research station and to my knowledge only the second for Ontario in 2005 (more sightings below).

Few birds but lots of rain....

Only 3 birds were banded from Saturday-Monday as rain kept us to just one-hour of mistnetting. That being said there were very few birds to capture anyway! New arrivals included Bank Swallow and Horned Lark.
 
We did manage to band 17 birds today which included the season's first Brown Thrasher and several Myrtle Warblers. A brief survey of the baselands produced more birds including 2 Northern Waterthrush, 1 "Western" Palm Warbler and 2 Yellow-bellied Sapsucker.

Dickcissel

A single Dickcissel was heard flying in the direction of the lighthouse around mid-morning today! This is the first of this species detected at TTPBRS.

White-throated Sparrow (Dan Derbyshire)

Migration Monitoring-April 15-21

The weather was very pleasant during the update period resulting in some meager totals for the week. A total of 90 net hours on the 15th yielded just 3 birds banded! Northern Rough-winged Swallow and Blue-winged Teal were season firsts on this day. A good variety of birds were banded on the 16th, however the overall total was still low at 27. The highlight of the day was a Silver-haired Bat found sleeping under one of the banding lab shutters! The 17th saw the arrival of Palm Warbler and Savannah Sparrow. For the first time this spring, Ruby-crowned Kinglet totals were higher than Golden-crowned. The 18th and 19th were quiet with approx. 20 birds banded/day. The first major increase in White-throated Sparrow numbers were evident on the 19th as 30 were tallied. New arrivals on the 20th were Northern Waterthrush, Brown Thrasher and Blue Jay. The day also featured a small influx of Myrtle Warblers. Eighteen birds were banded on April 21 which included a decent number of Hermit Thrush (7 banded). An American Bittern flew over the research station on this day, this is only the second record of this species for TTPBRS.
 
Below is an excerpt from the April 15-21 update in 2004 (Pine Warbler has yet to appear in 2005)
 
"The most notable data from the spring thus far has been a good showing for Pine Warbler, as 4-6 are being tallied on a daily basis (sometimes eclipsing Myrtles!)"

Migration Monitoring at TTP-April 8-14


Swamp Sparrow (Dan Derbyshire)
April 8-14 was an "up-and-down" week at Tommy Thompson Park. Calm conditions on April 8 failed to produce any major bird numbers as only 17 birds were banded. Glaucous Gulls were still being seen in decent numbers as 12 were spotted on what was left of the ice in the embayment. Significant movements of migrants were evident on both the 9th and 10th as 61 and 142 birds were banded respectively. Kinglets and Creepers were the dominant species. The return of north winds on the 11th spelled the end of the kinglet and creeper waves. Daily banding totals averaged about 10 birds/day from the 11th-14th. We are definitely in need of a change in the weather as clear skies and north winds have been unrelenting since last weekend.

Wednesday April 13-2005

After a busy weekend, migration has really cooled off at TTPBRS. Today we banded 12 birds and recaptured 10 more. The dominant species continues to be Golden-crowned Kinglet followed by Brown Creeper. I was surprised to note that only 27 Golden-crowned Kinglets were banded for the entire season last year. This spring we have banded around 300 and they are still going strong!
We still have yet to see any big pushes of sparrows, flickers and Myrtle Warblers. The first Barn Swallow of the season was detected on point count III flying along the embayment.

Migration Monitoring at TTP-April 1-7

This is the first installment of weekly updates for 2005 from the Tommy Thompson Park Migration Monitoring Program. As in 2004, our first day of coverage was April 1. It has been a rather long winter so it was really nice to be outside working with birds once again! April of last year was generally quiet due to a preponderance of north winds and cold temperatures. We were pleased to find more activity during the first week of April in 2005.
 
Warm temperatures on April 1 resulted in some respectable tallies of birds including: Winter Wren (4), Song Sparrow (20), Golden-crowned Kinglet (18) and Fox Sparrow (5). A total of 37 birds were banded on the first day. Wind and various forms of precipitation forced cancellation of fieldwork on the 2nd and 3rd. Only 5 birds were banded on April 4 due to strong north winds, however, a King Eider was spotted on census which is the first record of this species for the project! The banding remained slow on the 5th however there were 23 Glaucous Gull, 3 Iceland Gull and a sleepy Long-eared Owl on this day. Migration was much more impressive on April 6 when 92 birds were banded (63 were kinglets!) and a host of new arrivals were detected. Decent numbers of Brown Creeper and Slate-coloured Junco were also evident. Favourable conditions on the 7th resulted in 100 birds being banded (75% Golden-crowned Kinglet) and the arrival of Yellow-rumped Warbler and higher numbers of Tree Swallow.
 
A total of 249 birds were banded during the first week of spring which is substantially higher than the 42 tallied in 2004

April 5-2005

Staff and volunteers setup the research station on April 1st. We now have a very handy solar panel for the banding lab! The first day of banding was fairly active with 37 birds banded. The total mainly consisted of Golden-crowned Kinglet, American Tree Sparrow and Song Sparrow.
 
Highlights from today included a single King Eider, 22 Glaucous Gulls and 3 Iceland Gulls! The Eider and Icelands were new species for the TTPBRS checklist. The Eider was actually spotted yesterday on census by Seabrooke Leckie. Also seen today was a lone Long-eared Owl sleeping in the cottonwoods near nets 12 and 13. This is the second LEOW for TTPBRS. A quiet day on the whole but these sightings certainly made up for it.
 
A more detailed account of the week will be submitted on Friday.
