Two Horned Lark in January

This year we had above zero degree temperatures and green grass. The standing waters were mostly frozen and the moving waters were mostly open. We had 52 people out looking this year, they saw 64 species and a total of 11,992 birds. 1 Eastern Phoebe on count week.

This is consistent with last 2 years of 12,324 in 2017 and 11,501 in 2018. Over last 10 years we have averaged 76 species. We have seen a total of 114 species in last 10 years. Over the 71 years we have averaged 39 participants, 70 species and almost 15,000 birds with a grand total of 155 species seen.

George Prieksaitis got a Killdeer, which has only been reported in 9 of the 71 count years. The new high counts this year were Winter Wren (5), Redhead (2).

Wild Turkey did a poor showing with only 31, yet the 13 Turkey Vulture were a nice continuation since they seem to like over wintering in Port Stanley area in recent years. Does anyone know where they are roosting?

22 Bald Eagles this year, 6 Eastern Screech-Owl seen or heard and 3 Great Horned Owl.

Good sightings included 4 Belted Kingfisher, 51 Red-bellied Woodpecker. 39 Hairy Woodpecker approaching our high of 44. 7 Pileated Woodpecker, 14 Tufted Titmouse vs a high of 17 last year. 70 Eastern Bluebird, 7 American Robin, 22 Cedar Waxwing and 4 Eastern Towhee.

Conspicuous by their absence were Bonaparte’s Gull seen on 39 previous counts. Long-eared Owl seen on 47 previous counts. Northern Shrike and Field Sparrow proved to be elusive this year. Winter birds had a poor showing with only 8 Horned Lark, 10 Snow Bunting and no Lapland Longspur.

We would like to thank everyone who made the pot luck such a feast. Jackie and I appreciate all the effort everyone put into making this CBC a success and look forward to Dec 26, 2020.

North America down 3 BILLION birds

The Journal Science last fall reported that since 1970 North America is down 3 billion birds. We knew there was a problem. That is over 25% of the population. Only raptors with the elimination of DDT have made a massive recovery (over 200%), ducks and geese and vireos were the other real increase. Grassland birds suffered the most down 50%.

As December is upon us it is time to think about the 119th Annual Christmas Bird Count. This is St. Thomas’s 70th count. We will be doing the count on Boxing Day, Wednesday the 26th of December. This is the longest running citizen science project. Each year has new highs and a few surprise misses. We do our count in a 24 km circle. The volunteers can start any time they would like. There is a great pot luck dinner held at Knox Presbyterian Church at 55 Hincks St in St. Thomas after the count, doors open at 4:45 pm and supper at 6 p.m.

The Count is sponsored each year by Bird Studies Canada and National Audubon Society in the U.S. This year, the CBC will mobilize over 72,000 bird counters in more than 2,500 locations across the Western Hemisphere.

To learn more go to http://www.birdscanada.org/volunteer/cbc/

Audubon has a free Bird Guide app with over 800 species of North American birds, right in your pocket. The app is available for iPhone, Android and Amazon Fire tablets. This would be a good tool for the day.

The Christmas Bird Count is a tradition that everyone can participate in.
Birders of all ages are welcome to contribute to this fun community science project, which provided ornithologists with a crucial snapshot of our native bird populations during the winter months. To help count birds for science and participate in this year’s count.

The Tundra Swans have arrived at Aylmer Wildlife Management Area, part of their initial staging area. They are currently averaging about 1000 Swans a day.
The Elgin Stewardship Council was formed in 1997 and has been looking after the area since then and feeds the swans 23 to 25 bushels of shelled corn every day about 9 a.m. There are volunteers each day from 8:30 a.m. to 3:30 p.m. to answer any questions.

The Tundra’s spend almost a third of the year going from their wintering grounds around Chesapeake Bay and North Carolina to their nesting areas on the West coast of Hudson Bay, Central High arctic or the Mackenzie Delta, up to a 6000 kilometer journey.

Aylmer WMA has 4 viewing stands, 2 of which are open and 2 which are enclosed (1 wheelchair accessible). This area has been declared a globally Important Bird Area and the ponds a Provincially Significant Wetland. Aylmer WMA is perhaps the best place in North America to see Tundra Swans up close.

Aylmer WMA was originally #14 Service Flying Training School RCAF until 1961.

The Aylmer-Malahide Museum offer a Tundra Swan Line you can call and find out how many Tundra Swans are at Aylmer WMA on that day, call 519-773-SWAN(7926).

To get to Aylmer WMA via GPS use 10594 Hacienda Rd, Aylmer, ON.

2017 Christmas Bird Count

 
2018 CBC
 

The CBC took root over a century ago when 27 birders in 25 localities from Toronto, Ontario to Pacific Grove, California, led by ornithologist Frank Chapman, proposed a conservation-oriented alternative to the traditional ‘side hunt,’ a Christmas Day competition to hunt the most birds and small mammals. This alternative initiative to identify, count, and record all the birds found on Christmas Day 1900 has turned into one of North America’s longest-running wildlife monitoring programs.

St. Thomas has contributed since 1949, the 50th year of the original count, making this year the 69th count our club has participated in. We were over 1,000,000 birds counted in 2015. West Elgin participated 2 years earlier in 1947.

The day was cut a little short by the heavy fog in afternoon. We had new species of Dunlin found on beach in Port Bruce and Black Vulture spotted on beach at Port Stanley during count week. We had new highs with Golden Eagle(3), Peregrine Falcon(2), Robin(501) and Fox Sparrow(10). This year had over 100 American Bluebirds and 2 Great Horned Owls. Other nice sightings were Greater and Lesser Scaup, American Coot, Glaucous Gull, Merlin and a good number of Bald Eagles(20). The count has had Turkey Vultures every year this century with the addition of the Black Vulture this year. Ruffed Grouse have been conspicuously absent for a decade. Also missing were Snowy Owl and warblers.

Here is the Species Total in pdf form.

Hawk Cliff weekends wrapping up

The weather on Saturdays was wet to say the least. Last Sunday saw about 150 people attend the Raptor Bander and Monarch Watch demonstrations. This year saw the addition of a parking lot on the recently acquired Hawk Cliff Woods property by Thames Talbot Land Trust.
The trust had a large tent set up for the talks, which really worked well for the rainy days.
The Land Trust will be having their dedication and official opening of Hawk Cliff Woods at 12:30 on Sept 19th. All are welcome.

Hawk Cliff 2015 HawkWatch Summary

A few Hawk Cliff volunteers headed to the hawkwatch on August 21 to kick off the 2015 Hawk Cliff Hawkwatch season. Joined by many more in September, these volunteers eventually provided coverage until December 13, for a total of 117 count days, including 21 no-count days all of which were the result of inclement weather. In 2015, “inclement weather” usually meant rain, at times heavy, accompanied by strong southerly, (S, SW, SE) winds. Little snow was recorded during this hawk watch season, but observers did enjoy the unusually mild temperatures. Volunteers contributed a total of 518.25 hours, the highest number of hours’ coverage since the 2011 season. Again this year, our volunteers deserve a big thank-you for their dedication to the hawkwatch.

We’ve looked at the Birds per Hour (BPH) again for this summary which gives a truer feel for whether bird numbers were up or down compared to previous multi-year averages. This keeps the counts from being skewed by the assumption that the longer you spend on watch the more birds you see. This season we proved that assumption to be false. Compared to previous years, the 518.25 total hours for 2015 was only slightly below the past ten years’ average (539.20) so in terms of an average number of hours per day, we spent 4.47 hours per day for 117 days. Despite all those hours of observation, the total count in 2015 was only 53,559, far below the 15-year average of 67,246. Thus the total BPH was 103 for the season, much less than the 15-year average of 201 (2000-2014 inclusive).

The primary cause was the lack of a major Broadwing flight within range of observation from the hawkwatch. Our total for Broadwings was only 13,000 or only 10% of the highest count ever back in 2000 and well below the multi-year average of 33,400. Other species were also noticeably missing with our lowest ever count of Northern Goshawk (8) and nearly the lowest of Rough-legged (13). We did see our highest 1-day count ever though for Turkey Vultures (5,578) on Oct. 18, clearly a species that is not at risk in Ontario. All other species had lower BPH for 2015, many less than half the multi-year average. Let’s hope for bigger, better flights in 2016!
