Boundary Changes

If anyone out there is interested in the trifling small details of IBA boundaries, you will surely enjoy our new boundary for the Southwestern Mixed-grass Prairie IBA.

SW Mixed-grass IBA boundary change

Spot the difference. The green areas on the maps refer to areas of grassland. As you can see, there is a large section of grassland missing from the IBA in the southeast corner. This is the area known as the Blind Souris.

The changes were made to include the native prairies around the Blind Souris in the IBA boundary which were omitted originally. The Blind Souris has excellent habitat for grassland specialist birds including Ferruginous Hawk, Chestnut-collared Longspur and Sprague’s Pipit. This is not just a place for threatened birds, it also provides habitat for endangered plants, including some of the best remaining areas of Buffalograss in Manitoba (More info here).

We do not take boundary changes lightly and will only change them when there is a clear biological justification – we’re not politicians looking for electoral advantage after all!

This may not be the last word on this topic but for the meantime thanks to Andrew and Mike from Bird Studies Canada for acting on this.

So there we go, after the 1st blitz, the most numerous species is the American Coot at 1282 individuals followed by Blue-winged Teal and the trusty Mallards and a total of 132 species. It will be interesting to see how numbers change next month. We would probably expect fewer species but with more sparrows and very few, if any warblers still around. Canada Goose might possibly be expected to be the most abundant species and the numbers of shorebirds will also likely have fallen. All will be revealed on this site after the blitz and we can compare the changes in species types and abundance then.

All in all something to look forward to on October 3rd!

Misty beginnings to the Shoal Lakes IBA Bird Blitz

Saturday 29th August 2015 was our first bird migration blitz at the North, West and East Shoal Lakes IBA. 14 people made their way from WInnipeg, Gimli and further afield to take part. Tim Poole shares some memories and photos from the mornings birding.

Mist. Oh dear! Not the most auspicious start to the mornings birding activities. Surely things will improve soon?

Driving along West Shoal Lake, the mist hovering over the water, a Belted Kingfisher flies across the front and as the organizer, I am getting a wee bit concerned. Soon Garry Budyk and John Weier will be here to start counting and I haven’t got a didgeridoo (clue) how things are going to go. Apparently it took about an hour after our 7am start for Garry and John to get going. But things did improve (as evidenced below).

John and Garry would eventually be able to count good numbers or birds. in fact they managed to record 78 species and almost 1600 individuals. The section of West Shoal Lakes is a fantastic place for seeing ducks and shorebirds, even more-so in spring than fall.

The IBA was split into 7 survey sections, 4 to be accessed by vehicle, 1 by boat and 2 on foot.

The IBA was split into 7 survey sections, 4 to be accessed by vehicle, 1 by boat and 2 on foot.

14 people scattered in cars, foot, even a boat across the area. Optics galore and (from the evidence of the photos here), some rather good photographic gear. For anyone unfamiliar with the area, the Shoal Lakes IBA is in the Interlake area near Inwood. Originally this was a great place for Piping Plover but high water levels make it currently unsuitable for these rare birds. instead there are waterfowl aplenty, blackbirds, shorebirds and even the occasional Least Bittern (see here). Donna Martin is caretaker for this IBA and was also responsible for gaining the two donations which are funding these fall blitzes. Beforehand the big job was to recruit volunteers and provide maps of the survey sections which you can see to the left.

Donna was teamed up with Ray Methot and covered the north and west sides of North Shoal Lake. There were a fair few shorebirds in the area and another Least Bittern darted away.

I dropped Matt Gasner in rubber boots to walk across the washed out parts of Provincial Road 415, where he would meet Christian Artuso halfway. The following photos and captions are all from Christian and along with the captions tell the story of their birding highlights and endeavors along the flooded highway.

Common Yellowthroat_9566_artuso

Common Yellowthroat: There were many migratory warblers counted, presumably some migrants mixed with local-born Common Yellowthroats in the 54 I counted (before I joined up with Matt and there were many more after that).

Greater Yellowlegs_9667_Artuso

Greater Yellowlegs: we are deeply grateful to team yellowlegs for assisting in assessing the depth of water over the flooded road! No incidents occurred, other than a few wet pairs of socks.

Virginia Rail_9426_juv_Artuso

Sora_9766_juv_artuso

One of 51 Soras seen or heard, including many juveniles trotting about in the open (plus more after I joined up with Matt)

Northern Waterthrush_9600_artuso

The marsh seemed to be teeming with Northern Waterthrushes (this is one of 38 I counted by myself plus more again after I joined up with Matt)

While Christian and Matt were wading across an old highway, I was exploring another nearby road which might disappear at any moment. Needless to say, the mist reappeared before the road disappeared! I did manage one major achievemnet; that of getting the wettest feet of the day while trying to wade across a flooded section of road. I still managed to find 419 American Coots and 400+ ducks in the surrounding wetlands. Unbelievably, even though I eventually waded to the lake shore, I failed to enter the IBA! Later I would meet up with Christian and Matt counting another section with Semipalmated Plovers (37), Semipalmated Sandpiper (3), Least Sandpiper (2) and a single calling Long-billed Dowitcher.

While all this was going on, we had Bonnie Chartier roaming East Shoal Lake with Cam Meuckon from Manitoba Conservation on a boat. Special thanks to Cam for offering his time and the boat for the morning. Birding highlight? Scoters, ’nuff’ said!

Map of Cam's and Bonnie's route. Note how they seemed to spend most of their 'boat trip' on land especially to the north and east! This goes to show how much greater the water levels are now compared to where they were in the past.

Joanne Smith, Bill Rideout and Peter Douglas surveyed the eastern side of North Shoal Lake. They had the distinction of seeing a rather special couple of waterbirds….

Yes, that's right Trumpeter Swans. No, er, Tundra Swans, er, Tumpeter or is Trundra Swans? Ok, final they were Trumpeter Swans. Note the size difference with the adjacent Canada Geese, the long straight beak and lack of yellow on the lores below the eye. Photo copyright Bill Rideout

Apparently these guys must have started really early judging by this photo of the moon.

August is not known as a good time to do nocturnal owl surveys but that didn’t stop our intrepid surveyors from trying. Photo copyright Bill Rideout

One nameless member of the group spotted a Big Black Bear (new acronym BBB). Stoooooooooooooooooooop’ he/she yelled, ‘I see a bear’. The other group members turn to look but only see a field of cows. Admit it, we’ve all managed to confuse a cow and a bear!

BBB doesn’t just mean big black bear according to this group. It also means, big black blob (whatever that is) and big black bird (presumably the one below).

Again there were hosts of birds and much confusion to be found; yellowlegs, terns, ravens and warblers among a host of others.

Jo Swartz, Liis Veelma and Betsy Thorsteinson were our East Shoal Lake road team. They managed to achieve another birding highlight by hearing the secretive Yellow Rail calling very early on. Other birding highlights were Pectoral Sandpiper and American Pipit, the only group to locate these species on the blitz. I should apologise for sending this group up some pretty ropey roads looking for access points to the southern end of the lakes. Sorry!

Just before 1pm, a trail of us began to turn up at Rosie’s Cafe in Inwood for a late breakfast/brunch/lunch to share experiences and locations for a couple of species (the Trumpeter Swans were certainly revisited).

Thanks to everyone mentioned above for giving up your weekend to help out. The next blitz is on Saturday October 3rd. If you are interested in coming along for the ride please let me know at iba@naturemanitoba.ca.
