Photos from the annual local photographers’ walk around Minette Bay. The deepest cold passed, leaving ice everywhere. There was a heavy overcast and occasional fog.
Previous New Year’s walks
Went out to Whatl Creek on Wednesday morning as the Kitimat Valley Naturalists conducted the monthly bird count. At Whatl Creek swallows were darting from tree to tree, skimming the surface of the creek and hunting insects across the estuary since it was low tide.
Normally swallows are very difficult to capture, as I have tried a few times both this year and last with little success. At Whatl Creek, however, the photography gods were smiling. With the swallows skimming over the water, it was easier to follow them (than against the sky) and the autofocus was able to keep tracking the birds. Sony Alpha711, Sony 70-300mm G lens, ISO 2000, shutter priority 1/1250.
Here in Kitimat, you hear the “cooing” of doves more frequently these days.
The naturalists say the mourning dove (zenaida macroura)more common in southern British Columbia has been moving north, enticed by the changing climate. Other members of the family Columbidae that from time to time visit the Kitimat Valley are the band-tailed pigeon and most common pigeon of all, known as the rock pigeon or rock dove (Columba livia) even when it hangs out in city streets.
UPDATE: Since I posted this, I was pointed to a Kitimat area Facebook debate about the collared dove, which some people have seen in Kitimat over the past two years or so. (and complaining about the noise). This was the first collared dove I have seen although I have seen many mourning doves in the neighborhood.
Since the spring a white dove has been active in my neighbourhood, but with it usually perched high on the power lines, I couldn’t be sure what it was until a couple of days ago when it finally landed on my deck, near my feeder.

Clearly it’s a Eurasian collared dove (Streptopelia decaocto) which isn’t even listed in any of my British Columbia bird books. Wikipedia says the collared dove is native to “warm temperate and subtropical Asia from Turkey east to southern China and south through India to Sri Lanka” and began expanding its range across Europe and other parts of Asia in the early 20th century. The Eurasian collared dove has spread across China and into Japan.
According to Wikipedia a flock of Eurasian collared doves probably escaped from captivity in Nassau, the Bahamas in 1974 and arrived in North America proper in the 1980s with the first formal identification in Arkansas in 1989. The bird is now found all 48 contiguous US states. It appears to prefer the warmer climes of the more southern US states but with climate change it may be spreading further north.
The Eurasian collared dove prefers the same ecological niche as the mourning dove,
which if it isn’t a single vagrant or visitor (it appears to be sticking around) we may be seeing more around the valley. which likely means that like the mourning dove, the Eurasian collared dove is moving north as the climate warms.
This is how I usually saw the dove, high on the power lines. (Robin Rowland)
