A Note to IBA Manitoba Volunteers

As with many organizations, we are currently working to adapt our short and longer-term plans to deal with the realities of COVID-19. While indoor events that we have held in past springs are currently on hold, we are hoping to continue our work at outdoor events and activities under current government advice. If advice from the government changes, we will change our plans accordingly. As always we encourage volunteers to monitor IBAs using the IBA Protocol on eBird.ca (https://www.ibacanada.com/documents/eBird_IBA_protocol_EN.pdf) and continuing to count shorebirds under the International Shorebird Survey (https://importantbirdareasmb.ca/2018/08/13/the-international-shorebird-survey-iss-in-manitoba-an-encouraging-start/). We still hope that you will consider continuing to contribute to the program by monitoring independently in this way.

For now, Manitoba IBA continues to look forward to the spring and the arrival of our many feathered friends!

COSEWIC Updates in 2019

As we end off 2019 here is a quick overview of COSEWIC status changes for two birds that we see in our Manitoba Important Bird Areas.

COSEWIC (Committee on the Status of Endangered Wildlife in Canada) is an independent advisory panel that provides information to the Minister of Environment and Climate change in Canada. They are responsible for identifying and assessing the conservation status of wildlife species in Canada.

 

Hudsonian Godwit

This large shorebird was assessed by COSEWIC in May 2019 as “Threatened”. Previously it had no status under COSEWIC, and currently has no status under SARA Schedule 1. While populations on the breeding grounds are not well monitored, the monitoring on migration and the nonbreeding grounds indicate substantial recent population declines.

Hudsonian Godwit_0368

The Hudsonian Godwit breeds in the arctic, with its Manitoba range near Churchill. It is a long-distance migrant that travels to the southern third of South America. Northern Manitoba residents may see the Hudsonian Godwit during migration and breeding seasons in northern IBAs such as Nelson River Estuary and Marsh Point IBA and Kaskattama River Mouth IBA. Those of us in southern Manitoba can see the Hudsonian Godwit in our IBAs in Manitoba as they pass through in the spring and fall on migration.

Threats to the Hudsonian Godwit identified by the COSEWIC committee on the breeding ground include a decrease in suitability for nesting and prey availability due to climate change and an over abundance of geese. Threats at the nonbreeding grounds include loss of habitat and disturbance in South America.

In 2019 Hudsonian Godwits were seen at IBA events in both the spring and autumn at Whitewater Lake IBA. If you are interested in seeing Hudsonian Godwits and other shorebirds in 2020 be sure to stay on the lookout for our Shorebird Blitzes and/or International Shorebird Survey opportunities.

 

Chestnut-collared Longspur

Just last month (November 2019) the Chestnut-collard Longspur was reassessed from Threatened to Endangered by COSEWIC. It is still listed as Threatened under SARA Schedule 1. There has been a long-term decline of 95% of Chestnut-collared Longspurs since the 1970s. COSEWIC also lists a range contraction of the Chestnut-collared Longspur to the south and west. This fits with what we have seen in Manitoba where these birds can be seen in the southwestern corner of the province, when previously they were recorded near to Winnipeg and even at Oak Hammock Marsh according to The Birds of Manitoba.

In Manitoba this flashy grassland bird breeds in the southwestern corner of the province. It requires large continuous parcels of grassland for breeding. The Chestnut-collared Longspur’s nonbreeding range extends throughout the southwestern United States and into northern Mexico.

The main threat identified by COSEWIC for the Chestnut-collared Longspur is habitat loss, degradation and fragmentation. This is impacting the Longspur in both its breeding ground in Canada, as well as its nonbreeding range in northern Mexico.

Both the Southwestern Mixed-grass Prairie IBA and the Ellis-Archie and Spy Hill Community Pastures IBA have held continentally important occurrences of the Chestnut-collared Longspur in recent summers.

New Manitoba IBA Coordinator

Hello everyone, my name is Amanda and I am just starting work as the new Important Birds Area coordinator. I have been a volunteer for the IBA program at several blitzes over the past couple of years so we may be familiar faces to each other. Prior to this position I was working as an environmental policy analyst in Manitoba, but my passion has been birds for many years. I completed my undergraduate degree at the University of Manitoba with work terms at Agriculture and Agri-Foods Canada as a riparian health technician and at Ducks Unlimited Canada working on the Carp Exclusion Project at Delta Marsh, Manitoba. It was working and living in the middle of Delta Marsh during two springs and summers that my interest in birds took flight.

From 2015-2017 I complete my M.Sc. degree at the University of Manitoba in the Avian Behavior and Conservation lab. There I studied purple martins, a long-distance migratory bird that catches insects on the wing (aerial insectivore). Recent publications have detailed how aerial insectivores and long-distance migrants are both showing population declines. For purple martins, like many insectivorous birds, it is important that they arrive at the breeding grounds when weather is nice enough to allow for insects to emerge. If birds arrive too early a lack of food and cold weather decrease breeding success, while arriving too late may mean that they do not have enough time and resources to raise their young before autumn migration.

As climate change progresses in North America we are expecting earlier springs and warmer temperatures. If purple martins do not adjust spring arrival timing it may lead to a mismatch, where martins become out of sync with their environment at the breeding grounds, unless they are able to adapt. My work was to examine how purple martin migration and breeding timing may be affected by climate change across North America.

My work involved two approaches both which could only be done with the help of citizen scientists locally and across North America. The first was working on the ground in Manitoba with local citizen scientists to deploy light-level tracking devices, called geolocators, on purple martins. These tracking devices weight less than 5% of a bird’s body mass and use sun rise/sun set and solar noon to estimate latitude and longitude. The tracking devices are put on the birds during the breeding season and retrieved in the following year (they do not transmit data). Luckily for us purple martins generally return to the same breeding sites each year.

Geolocators give us a location for each day they are on the bird, so that we can track time and place of fall roosts, migrations and overwintering sites of these birds as they migrate to the Amazon each year. Overall, I found that spring temperatures along migration did not predict martin migration timing. Instead individual birds had highly similar migration time between different years of spring migration, suggesting that migration timing may be inherent to individuals rather than directed by weather en route.

I also used a data set collected by citizen scientists across North American over 20 years through the Purple Martin Conservation Association’s Project MartinWatch. Citizen scientists monitor purple martin colonies throughout the breeding season for egg-laying, hatching and fledging timing and numbers of young. With this dataset I determined that purple martins lay earlier in warmer springs and fledge more young when they lay earlier. I found that selection favoured earlier breeding in most years but there was not increasing pressure to select for earlier breeding over the 20-year period. This suggests that purple martins may be able to adjust their breeding timing to earlier spring conditions. However, if breeding trends continue to become earlier, eventually breeding timing might be limited by the arrival date of purple martins at their breeding grounds from spring migration.

In my roles as a researcher using data collected by citizen scientists, and as a volunteer citizen scientist myself, I have seen firsthand the importance of work done by the public plays in the scientific process. So often science is constrained by time and resources, so the knowledge and help provided by citizen scientists working together provides valuable information and different viewpoints than any one person working alone. If you are interested in joining our team of volunteers, I would love to hear from you at iba@naturemanitoba.ca or (204) 943-9029.

Research engagement opportunity for landowners and livestock producers in Southwestern Manitoba

The Manitoba IBA program is excited to announce the launch of a new research project aimed at understanding livestock producer and landowner motivations for engaging in grassland conservation activities. Because much of Manitoba’s high-quality native grasslands are privately owned, it is essential that conservation organisations are able to work collaboratively with the people who own and work on the land. That is why the Manitoba IBA Program and Bird Studies Canada, with the support of Manitoba Habitat and Heritage Corporation, West Souris River Conservation District, and Turtle Mountain Conservation District will seek to recruit landowners and producers to participate in an online survey. Participation in this survey will help us understand local people’s environmental values and views on avian Species-At-Risk. Through better understanding landowners and producers, we hope to identify practical ways of addressing conservation issues in Southwestern Manitoba.

Southwestern Manitoba is a stronghold for much of the province’s remaining high-quality mixed-grass prairie habitats. Four Manitoba Important Bird Areas (IBAs) can be found in the Southwest, including our newest addition: Ellice-Archie and Spy Hill Community Pastures Important Bird and Biodiversity Area. The three other IBAs include: Whitewater Lake, Oak Lake/Plum Lakes, and Southwestern Manitoba Mixed-Grass Prairie.  Southwestern Manitoba is home to many avian Species-At-Risk, such as the Chestnut-collared Longspur, Sprague’s Pipit, Baird’s Sparrow, Loggerhead Shrike, and Ferruginous Hawk.

In the spring of this year, the 12th Prairie Conservation and Endangered Species Conference (PCESC) took place in Winnipeg. The theme of this conference was “working landscapes”, in acknowledgement of the fundamental role that landowners and producers play in grassland conservation across the prairie provinces. Helping landowners and producers retain and manage grassland properties is vital for supporting the retention and recovery of our grassland Species-At-Risk.

If you are a landowner or livestock producer in Southwestern Manitoba and would like to participate in this project, you may proceed to the online survey HERE. Surveys must be completed by November 10th, 2019. Participants will also have a chance to enter a contest to win a $100 pre-paid VISA card (winning ballot will be drawn on November 25th, 2019).

Lynnea Parker is the coordinator for this project and she can be reached by email at assistant.manitobaiba@gmail.com or by phone at 1-204-558-0559.

Funding for this research project has been provided by Bird Studies Canada through the Manitoba Conservation Trust and a Young Professional Stewardship grant awarded at the PCESC this spring.

The Shorebird Blitz at Whitewater Lake, September 1st 2019

On September 1st, the Manitoba IBA Program organised a blitz at the Whitewater Lake IBA. The intention was to count shorebirds, including the International Shorebird Survey (ISS) transect routes. Bonnie Chartier, one of our IBA Steering Committee members in Manitoba led the trip. Tim Poole, (still) the Manitoba IBA Coordinator gives a summary of proceedings.

Alas I was unable to get out for the Whitewater Lake IBA Blitz and it sounds as though I missed a good one! We had to postpone from the previous weekend due to some appalling weather. Seriously, there seemed to be a magnet for poor weather to overlap with IBA events in 2019. We have never had so many issues with weather before! Although it was a long weekend, 12 willing volunteers were able to get out and count the great birds of this IBA.

Each group was asked to cover an area, and two groups were asked to include ISS routes and enter these under the ISS Protocol on eBird, with the Manitoba IBA Program switching  all checklists into IBA Protocol. This eBird malarkey gets complicated! We had four groups with some excellent birders coming forward to help out during the morning.

Our summary of the day begins with Group A, the western group, covering the western ISS route and the parts of the IBA around Deloraine. Gillian, Erica and Jane were our team here.

WWL-West Route Map

This area has previously been teeming with birds. However seven species of duck demonstrates that maybe times are a changing at Whitewater. The most abundant duck was Blue-winged Teal (102 individuals). Indeed, long-legged waders seem in short supply, especially when compared to previous years. I would have fallen over backwards during one of our 2017 blitzes if someone were to tell me there would only be three White-faced Ibis, a Great Egret and not a single Cattle Egret in this area in 2019.

Shorebirds were fairly abundant, although maybe, being late summer, numbers were lower than earlier in the season. Still, 300 dowitchers remains a good total. There were also 18 Red-necked Phalarope, 27 Pectoral Sandpiper and 65 Least Sandpiper, part of a total of 14 species for the morning.

Group B included blitz leader for the day, the indefatigable Bonnie. She was joined by Glennis and Lynnea for the morning. One surprise was a Ferruginous Hawk. The story goes that Bonnie called Ferruginous Hawk, someone else who shall remain nameless called Krider’s Hawk but took a photo, and lo and behold Ferruginous won.

This made it  four Buteo species morning, with Red-tails, Swainson’s and Rough-legged also identified. There were reasonable numbers of Canada Goose (316), Blue-winged Teal (197) and Mallard (151). The number of species of duck (five in this case, and all dabblers) was low across the board, many must still be on their moulting grounds. For example, thousands of Canvasback and Redhead moult in the Long Island and Long Island Bay IBA and the Sagemace and Coleman Bay Islands IBA.

Of course the subject of the blitz was to capture those all important shorebirds. We set this group along the eastward ISS transects and they also had time to cover the all important Sexton’s Island ISS, plus the considerable stretch of PR448 in-between.

WWL_East Route Map (1)

In total Group B counted 17 species of shorebird. Sexton’s was quiet, just a single Black-bellied Plover with a handful of yellowlegs and Killdeer for company. The really big numbers were in the east, with 443 American Avocet, 277 White-rumped Sandpiper, 681 Semipalmated Sandpiper, 170 Short-billed Dowitcher and 140 Long-billed Dowitcher. The peaks of Pectoral Sandpiper had clearly been and gone from Whitewater Lake, only 13 counted in this area.

Group C were first time blitzers Tami and Mike with more experienced pros Lewis and Ken. This group took on an area starting in the southeast and stretching west of the old mound. They had some decent numbers, including 255 Stilt Sandpipers at the end of 124W.

They also had 66 American Avocet.

Canada Goose (864) and Red-winged Blackbird (1081) were unsurprisingly the most abundant birds in their area. A Prairie Falcon was a very nice bonus bird.

Group D were the Moois, Randy and Odette. Randy being a zoologist as well as a very good birder, had great fund photographing anything that he could find. From caddis flies….

Grebe numbers, most notably Western Grebe appear to have been low at Whitewater Lake in 2019. In 2017, Randy and Tim counted over 1,000 Western Grebes in this area. In 2019 there was only a single bird, plus a Pied-billed and two Eared.

Shorebird numbers were very good in Area D. There were 177 Stilt Sandpiper, plus over 250 of both species of dowitcher (due to the complexities of distinguishing between these species, most remained unidentified).

Three Buff-breasted Sandpiper were encountered as well. Another highlight were the two Hudsonian Godwit, a threatened species in Canada, and also relatively rare to encounter in this region during fall migration.

In total this group encountered 17 species of shorebird during the morning, an impressive total! They also saw another single Prairie Falcon and 19 White-faced Ibis.

In total, our volunteers counted over 13,000 birds, representing 98 species. The most abundant species was Canada Goose (1,969), followed by Red-winged Blackbird (1,704). It would appear there has already been some evidence of migration of Yellow-headed Blackbird, as usually numbers of this species in fall re much higher. Diving ducks are still to gather here in any significant numbers, but there were good totals of dabblers. Grebe numbers and long-legged waders appear very low compared to past counts, and this must be associated with the fast changing water levels. The lake does at last seem to be rescinding from the peaks a few years ago. We also missed the peak swallow migration because in previous years they were hard to count! One group of birds seemingly doing ok here are raptors, there being over one hundred counted.

Shorebirds were our target group of birds. Semipalmated Sandpiper gather at Whitewater in very good numbers in fall, and were the most abundant species (706). There were 549 American Avocet counted, 448 Stilt Sandpipers, 302 White-rumped Sandpiper and 186 Lesser Yellowlegs. Dowitchers totaled nearly 900, but most were unidentifiable.

September IBA Contest Sponsored by Red River Coop

IBA birding contest September.jpg

September is a great month for raptor migration in Manitoba’s IBAs. You can also enter by submitting observations through our website at https://importantbirdareasmb.ca/submit-your-observations-comments/. At the end of the month we will do a draw of all eligible checklists for an opportunity to win a $50 gas card from Co-op, donated by Red River Co-op.

Augusts contest was won by Barbara and Phil Barnett for this checklist from Delta Marsh IBA – https://ebird.org/canada/view/checklist/S59381530.
