Just look at those toenails

Five birding friends and I had a most enjoyable day trip east of Calgary on 16 April 2016. The weather was gorgeous, with perfect clouds that were reflected in every pond/slough/wetland that we came across before the breeze disturbed the water.

I think the main highlights for me were a Western Meadowlark that flew to a tall post just about within camera reach; a mixed pair of Red-tailed Hawks (one light morph and the other dark) perched together in a far away tree; and a beautiful LEUCISTIC Merlin (i.e. paler than it should be) that three of us were lucky enough to see after the group split up to start our journey back to Calgary. It was enjoying a snack on top of a very tall utility pole. Also, this little Muskrat was fun to to watch along the shore at Chestermere Lake.

"An adult muskrat is about 40 to 60 cm (16 to 24 inches) long, almost half of that tail, and weighs from 0.7 to 1.8 kg (1.5 to 4 lb). Muskrats are much smaller than beavers (Castor canadensis), with whom they often share their habitat." From Wikipedia.

"Leucism is an abnormal plumage condition caused by a genetic mutation that prevents pigment, particularly melanin, from being properly deposited on a bird’s feathers. As a result, the birds do not have the normal, classic plumage colors listed in field guides, and instead the plumage have several color changes, including white patches where the bird should not have any; paler overall plumage that looks faint, diluted or bleached; or overall white plumage with little or no color discernable."

Our leader, Terry Korolyk, always writes such a detailed account of each trip, so there is no point in my repeating some of the information. Many thanks for another great day (including the write-up), Terry, and many thanks, Tony, for the ride!

“Today's Nature Calgary Field Trip had beautiful weather for its trip east of Calgary. We met just west of the Rowing Club around 9:30 A.M., checking the Reservoir there firstly, then, heading east on Glenmore Trail. The only bird of note on the Reservoir was a Common Loon in the bay at the Yacht Club. We then headed east on Glenmore Trail turning south on Stoney Trail going as far as 114 Avenue where we turned left driving to 84 Street, then, going south to Ralph Klein Park. Birds of particular interest at the Park included American Avocet, Black-necked Stilt and, Lesser Yellowlegs, the latter of which we had the pleasure of observing a couple of flocks of significant size one of at least 70 birds fly in. This was a particularly good sign for the day as we saw many Yellowlegs totalling 227 birds in the final analysis.

From Ralph Klein Park, we kept south on 84 Street to 146 Avenue where we turned east driving to Range Road 284 where we turned north checking sloughs along the way to Township Road 232 where we turned we turned east, then north on to Range Road 283. We followed Range Road 283 to Chestermere Lake stopping at the Dam; then Sunset Park on the east side of the Lake; then, the north end of the Lake north of Highway 1A. From there, we drove under the Trans-Canada Highway through the subdivision on the east side of the Highway to McElroy Slough. From McElroy Slough, we kept eastward on Inverlake Road driving to Highway 9, then, from Highway 9 south to Highway 560, turning east at the 4-way junction there driving to Weed Lake. From Weed Lake, we headed westward towards Calgary checking a slough at the Highway 560-Range Road 284 junction, then, from there we stayed westward to Stoney Trail turning north on Stoney Trail turning off at Peigan Trail, then westward on Peigan past the City of Calgary Landfill.

We had many highlights; the most important of which was a mixed pair of Red-tailed Hawks. Of the pair, one adult was a RUFOUS MORPH bird; the other was a light-phase EASTERN RED-TAIL. The pair were together, but, I cannot divulge the location as this a sensitive pairing (rare). You can contact me if you wish more details. The birds have nested at this site previously. I did not see them there in 2015, but, saw them there previously 2 out of 3 years. I believe young were probably raised in at least one year; the year when the JAEGERS were at Weed Lake (POMARINE and PARASITIC). I believe it was 2013. At that time while going out to the Lake I noticed at least 3 rather unusual-looking Red-tails on the west side of Weed Lake and west of Weed Lake.

Other highlights were an ALBINISTIC American Wigeon at a slough on Range Road 280 just south of Inverlake Road. The bird had 2 large white clear patches on each side; an incredible LEUCISTIC MERLIN photographed by Tony Timmons at the 4- way stop in Langdon (it looked like a miniature white-morph Gyrfalcon with a banded tail); five hybrid TUNDRA-TRUMPETER SWANS at McElroy Slough, and 50 AMERICAN PIPITS at a shallow wetland on 146 Avenue just east of 104 Street.

Northern Pintail was the most numerous Duck of the day with 1621; American Wigeon came in at 1017; and, Northern Shoveler came in at 962. BLACK-NECKED STILTS and AMERICAN AVOCETS were a particularly wonderful sight at the south end of Weed Lake and at Langdon Corner Slough, which is at the Highways 1 and 9 junction.

Two SWALLOWS were seen briefly at the Dam at Chestermere Lake, but, we were unable to identify them. One other DARK MORPH Red-tailed Hawk was seen, and 4 American Kestrels were seen.

The City of Calgary Landfill had excellent numbers of Gulls; I would estimate their numbers at 1500 for anyone interested in doing some Gullwatching this coming week.”
