Notes for March 24, 2016
About
a week after last month’s column appeared, the first avian heralds of spring
appeared. Common Grackles and Red-winged Blackbirds swarmed backyard feeders,
eating furiously to recover from their migration from the southern U.S.
Many
observers also started reporting American Robins. Although a few have been
around all winter, some of these were newly returned migrants. For most of the
winter, I have had a robin spending a lot of time in the mountain ash tree in
my front yard. This bird is so used to us that he doesn’t even fly when we
drive in the driveway and get out of the car. He just “chucks” at us a couple
of times and goes back to eating the fallen mountain ash berries. If this is
the same bird, he has recently acquired a mate. We’ve seen a female with him
this past week.
Waterfowl
are among the earliest migrants. They require open water, so follow the thawing
ice as temperatures warm in the spring. Presqu’ile Provincial Park’s Waterfowl Festival
was last weekend (March 19 and 20). Because of the mild spring, the lake and
Presqu’ile Bay were ice free. Although there were waterfowl present, they were
quite far out on the bay. Even with a spotting scope, they were difficult to
see. Many of the ducks and geese have already moved further north. The huge
rafts of Redhead and scaup that were present almost three week ago have mostly
departed.
My
husband, Roger, and I volunteered to man a viewing platform last Sunday for the
Festival. Although ducks were scarce, we had some other good sightings. Just
after we arrived at our post, a Peregrine Falcon flew through. It was very
ambitious, making a run at a Canada Goose! It didn’t get the goose – no
surprise here – but thoroughly frightened the small Bufflehead that were feeding
nearby. When the Bufflehead took flight, we had a better idea of how many there
were. Diving ducks are very difficult to count when they are feeding because
only seldom are all of them on the surface at the same time.
Later
in the morning, two Sandhill Cranes flew past our platform, calling loudly.
They circled around and looked like they might land in the marsh, but circled
again and flew away to the east. Sandhill Cranes are becoming more common in
southern Ontario, so there is a chance that readers might encounter one. When
they are courting, they are very noisy, so are easy to detect.
Two
Pied-billed Grebes entertained viewers quite near the viewing platform. These
small grebes nest in Presqu’ile marsh.
The
previous week, Willow Beach Field Naturalists held an outing to search for
waterfowl. Rice Lake was still partly ice-covered, with open leads. Off Harwood
the group found a good variety of ducks – Common Mergansers, Hooded Mergansers,
Ring-necked Ducks, Common Goldeneyes and Northern Pintails, in addition to the
ubiquitous Canada Geese.
GardenHill Pond held a surprise – a single Greater White-fronted Goose amongst the
hordes of Canada Geese. There were also a few Cackling Geese. These are a small
species of Canada Geese that have recently been designated as a separate
species. There were also Northern Pintail, several Green-winged Teal and
American Wigeon here.

Many
of us had our first Song Sparrows of the season on this outing. A Killdeer also
appeared that day, calling its name as it flew over. A Belted Kingfisher was
fishing in Close Point marsh.
On
March 17, an American Woodcock, another early migrant, was calling at the A.K.Sculthorpe Woodland Marsh. Woodcock probe with their long beaks into the soil
to feed on earthworms and insects. Immediately after this date, there were two
very cold nights. If the ground froze again, this bird may regret that he
migrated quite so early.
Although
the weather forecast predicts a return of wintry weather by the end of the
week (when this will be published) the birds tell us that spring is here.
