On Sunday, May 6th, 14 birders split into 4 groups and covered over 177 km of the North, West, and East Shoal Lakes IBA (IBA map). With a late start to spring this year we were not sure what to expect in terms of species diversity and numbers. On Saturday, the day before the blitz, Tim Poole and Lynnea Parker noted that ice coverage on Lake Manitoba was still quite extensive at Sandy Bay Marshes IBA near Langruth. Lynnea was therefore glad to observe that West and East Shoal Lakes were mostly ice-free. North Shoal Lake was partially open along the roadsides and marshes.
122 species were observed in the morning with good numbers of waterfowl and grebes. Group 1 with Pierre, Bill, Wally, and William were particularly fond of the 171 American Robins and 159 Red-winged Blackbirds they thoroughly counted. However, the robins and blackbirds paled in comparison to the 611 Western Grebes which were spotted rafting together at West Shoal Lake (Group 1 checklist).
At the Sandy Bay Grebe Watch event on May 5th, Tim and Lynnea had been hoping to see several hundred Western Grebes. Due to the heavy ice cover, only 112 Western Grebes were counted. It would seem our missing Grebes were over at West Shoal Lake instead! A further 500 were spotted by Bob Jones at Delta Marsh the previous day.
Group 2 with Jo, Betsy, Christian, and Mohammad surveyed the east side of East and North Shoal Lakes. Christian turned back the clock and took up his Atlas nickname ‘Moose Legs’, walking the rejuvenated wetland also known as PR415, which runs between North and East Shoal Lakes (Christian’s Checklist). The decommissioned, and partially flooded road was highly productive with 94 species, including high counts of waterfowl, Double-crested Cormorant, American White Pelican, American Coot, Sandhill Crane, Gulls, and Blackbirds. Unfortunately for Christian, he missed the Snowy Egret spied by Group #4 which was found on the same decommissioned road just outside his survey area to the west. Group #4 didn’t feel bad however, as Christian managed to find a Clark’s Grebe which they didn’t see. Photos below feature a pair of Lesser Yellowlegs (upper left), pair of Canvasbacks (middle left), flock of American White Pelicans (lower left), and a Marbled Godwit preening (right) (photos by Christian Artuso). (Additional checklists for this group: #1, #2, #3, #4, #5)
Group 3 with Joanne, Richard, Louise, and Eric surveyed the IBA area north of North Shoal Lake. They had many species of waterbirds despite having less open water in their area. Good sights from Group 3 included 4 Trumpeter Swans, 18 Red-necked Grebes, and 1 Semipalmated Plover (Checklist). The photos below by Joanne Smith include Red-necked Grebe (Left) and Willet (Right).
Group 4 with Lynnea, Cam, and Jeff surveyed the northern part of West Shoal Lake, west side of East Shoal Lake, and west side of North Shoal Lake. The highlights from this group included a Snowy Egret, good numbers of Green-winged Teal and Blue-winged Teal, and 11 Great Egret. Access to the open water was limited, but the marshy areas were moderately productive. Photos below were taken by Cam Nikkel and feature a Forster’s Tern (Left) and a Great Egret (Right).
Overall, highlights of the day included: 13 Greater White-fronted Goose, 766 Western Grebe, 1 Clark’s Grbe, 490 American White Pelican, 6 American Bittern, 32 Great Egret, 1 Snowy Egret, 3 Black-crowned Night-Heron, 116 Sandhill Crane, and 58 Bonaparte’s Gull.
After the morning blitz everyone gathered at Rosie’s Cafe in Inwood for a glorious lunch before wrapping up the event.
