Teslin Lake update - October 15

The nights are getting colder and the lake foggier

There was still a good number of passerines around early October as there were kinglets, chickadees, sparrows and even some warblers flitting in the bushes of TLBO. Unfortunately the banding season came to an unexpected halt after Oct 2nd when the promised help didn't show up. A few nets were opened every once in a while for short periods of time when visible migration was very slow and the very last banding effort was made on Oct 11 when Ted Murphy-Kelly came to help out with taking down the station. That and the following day we managed to pack the tents and all the netting related gear except for the canopy net structure. As for the birds banded, 104 more birds received some jewellery in October. Perhaps the most exciting ones were the two Northern Waterthrushes (Oct 1st and Oct 3rd, one of them staying until the 5th!) as they were the first October records for TLBO. The species is normally quite uncommon already in early September! The season 2nd Gray-cheeked and Hermit Thrushes were banded on the 2nd. The final season top five is as follows - Alder Flycatcher 770, Dark-eyed Junco 341, Yellow Warbler 333, Yellow-rumped Warbler 163 and Ruby-crowned Kinglet 125. Overall it was the second poorest year (of the full operation years) in terms of number of birds banded at TLBO. Five species were banded in record low numbers - Sharp-shinned Hawk, Hermit Thrush, Wilson's Warbler, White-crowned Sparrow and Common Redpoll. Three species were banded in record high numbers - Northern Flicker, Warbling Vireo and Cedar Waxwing. Other species with higher than average numbers included Yellow-bellied and Alder Flycatcher, Swainson's Thrush and Dark-eyed Junco.

Early to mid-October is normally one of the busiest and most exciting times at TLBO with visible migration and rarities. However, this year no rarities were spotted and the migration for the most part was pretty disappointing. The last big day of "dickie bird" migration was Oct 1st when nearly 1500 American Robins were counted alongside 1300 other passerines including 90 Yellow-rumped Warblers, 270 Pine Siskins and an observatory record of 296 Rusty Blackbirds! 69 Rusties on the 7th was the last high count for that species. 215 Bohemian Waxwings flew by on the 4th and about 100 roamed the area on the 15th. Usually the big thing at this time of the year are the thousands of swans passing by. This year no such thing has been seen. So far the busiest swan day was the 10th when about 800, mostly Tundra Swans,  were counted. 215 Trumpeter Swans were seen the next day and another 150 were tallied on the 15th. Other waterfowl of interest during the period included a late flight of 112 Lesser Scaup and a lone late Snow Goose on the 10th and three Harlequin Ducks on the 11th. October is typically the time of eagles as well. This year there have been very few Bald Eagles seen, perhaps because many left earlier, but it has been quite good with Golden Eagles. The highest day counts so far have been 31 on the 4th, 37 on the 5th and observatory record 86 on the stormy day of the 9th. Finally, birds behind the usual departure dates included a Bonaparte's Gull on the 5th and a Wilson's Warbler on the 12th.

  This season's longest serving volunteer, Sarah Coulthart, left us on the 2nd. Thank you Sarah for all your help and we applaud your endurance as you now hold the observatory record for most consecutive days spent in a tent at the site! The same day saw another volunteer, a published author Chris Sukha (The Mini-Mentor Guide To Birdwatching for Beginners) leave as well. Chris had spent a full season at Mackenzie Nature Observatory in BC and after Mackenzie season ended he came and helped us out for a week. Thanks Chris for spotting all the specks in the sky!

Teslin Lake update - September 30

In September Yukon turns Yellow!

The last third of September was very quiet time with the nets - even when we could operate them. The weather was very unsettled with lots of rain and especially wind, and on many days we had the nets open for just an hour or so and usually not all the nets either. As a result, only 107 birds were banded. 35 of those were Dark-eyed Juncos and 30 Ruby-crowned Kinglets. A Hammond's Flycatcher on the 23rd and an Alder Flycatcher on the 25th were both a little bit on the late side.

 

Most of the Bald Eagles seen as part of the record flights were immatures of various ages

Ospreys were seen on most days but usually in small numbers

No rare or even uncommon birds were seen but there was lots of action in the sky especially early in the period. Most of the good flights were those of raptors. On the 21st 149 raptors were seen including a new observatory day-record of 30 Bald Eagles. The next day the raptor tally was 278 this time including 185 Sharp-shinned Hawks which also was a new day-record. Luckily most of the raptor movement was in the afternoon since in the morning we were almost overwhelmed by the flight of American Robins and other passerines. A total count for Robin/Varied Thrush (about 90% Robins) was 5900! 1700 other passerines, including identifications of 85 Bohemian Waxwings, 164 Rusty Blackbirds and 67 Pine Siskins, were also tallied and as if that wasn't enough somewhere in between we noticed almost 400 Canada Geese fly by. On the 23rd we counted 125 raptors, 800 Robins and 156 Rusty Blackbirds but the day will really be remembered from its 1025 Pacific Loons - a count far exceeding the previous record. A cold and strong northwest wind was blowing on the 24th and it brought another 253 raptors with it. Bald Eagles reached the count of 30 again while other good tallies included 118 Sharp-shinned Hawks and 46 Red-tailed Hawks. The day was also the first one of the fall with some swan movement (200) and two nice flocks of Snow Geese totalling 116 birds were seen as well. All this activity was followed by five days of pretty much complete nothingness until on the 30th birds were moving again. That day 280 raptors, including 44 Golden Eagles, 112 Sharp-shinned Hawks and 22 Rough-legged Hawks, were counted. Other big birds spotted heading south included 400 Tundra Swans and 111 Sandhill Cranes.

On the morning of the 30th bear tracks led from the creek mouth through the banding site. This present was left at net #18!

Donald (R), a Scottish traveller, loved the site so that he spent two days with us. He had a wish list of two species, Golden Eagle and Peregrine Falcon, and he got to see both!

 

On the 28th we all headed to Whitehorse for the SOYBO annual get-together. It was a great party and thanks for Ted and Hollie for hosting it. The next morning we brought Abril to the airport and said good byes before heading back to TLBO. Thank you Abril for yet another great season!

Teslin Lake update - Sept 20

Male American Three-toed Woodpecker - the 1st ever banded at TLBO!

The mid-September period at TLBO was an exciting one particularly with the migration watch. The weather again wasn't our friend and so the banding totals remained rather low. However, one bird out of the 257 banded, an American Three-toed Woodpecker on the 12th, was of special interest as it was, quite surprisingly mind you, the first ever banded at TLBO! Other highlights from the nets included a Dusky Flycatcher and a latish Swainson's Thrush, both also on the 12th. The top five for the period was Dark-eyed Junco (106), Ruby-crowned Kinglet (41), Orange-crowned Warbler (21), Yellow-rumped Warbler (17) and Yellow Warbler (16).

 

1...2...3!

 

The most exciting bird of the period was a beautiful full-tailed adult Long-tailed Jaeger seen on the 11th. To everyone's surprise, the bird was spotted again on the 12th and later seen departing towards the east over the mountains instead of the west and the Pacific!

 

The longer the tail...

As the weather was turning colder more northern birds started to head south. New species for the season were Black-backed Woodpecker on the 11th, Tundra Swan and Long-tailed Duck on the 14th, Rough-legged Hawk , Glaucous Gull and Mountain Bluebird on the 18th and Northern Hawk Owl on the 19th.

 At least six Parasitic Jaegers, including two rare dark-morph ones, were seen prowling the lake on the 11th. The same day count of 29 Red-throated Loons was just three short of our day record for the species. During the second half of the period we had several busy migration days. On the 15th 235 Canada Geese flew by as well as 42 Red-tailed Hawks (70 raptors in total). Thanks to the poor visibility, low hanging clouds and strong south wind on the 18th many Pacific-bound birds like 150 Pacific Loons and 55 Thayer's Gulls were forced to fly low enough for us to spot them. The same day record tying 11 Peregrine Falcons were seen. Nine more followed the next day and six more the day after - wow! The 19th was quite a day with 5200 American Robins/Varied Thrushes and 1550 small passerines (mostly unidentified but identifications including 43 American Pipits, 53 Yellow-rumped Warblers and 114 Rusty Blackbirds)!! Also seen were 32 Northern Harriers (74 raptors in total). Finally, a jaw-dropping flock of 190 Rusty Blackbirds was foraging on the shoreline on the 20th!
