Carburn Park Part 2: Bow river gravel bars and the north ponds

Posted by Dan Arndt

Our second week at Carburn Park took us to the north end, usually a good spot for us to find migrating swallows, blackbirds, and usually warblers. This week was no exception though the usual numbers that we expect were a little low, I suspect because of the rather warm spring we’ve had and the significant amount of open water elsewhere in the foothills.

From the parking lot, we again headed south to the bridge, where we heard the ongoing and always happy sounding song of Ruby-crowned Kinglet. This happy little fellow and his kin are always hard to get out in the open, but today we managed a few moments with him out at the edge of a bush, and with his ruby crown raised too!

We followed the edge of the Bow River in search of the usual swallows and warblers, and while we didn’t manage to get very good or long looks at many of them, we did spot a number of Tree Swallows and a lone Violet-green Swallow in among them. Even better was this rather handsome male Common Merganser, his iridescence shining in the sunlight as he floated past.

As we headed up-river, we heard many migrating Song Sparrows on the near and far banks, and even had a lone Yellow-rumped Warbler in the dense shrubs west of the second pond, though none of us managed to see it, his song was heard loud and clear. And while we didn’t find the Wood Ducks again that week, we did get really good looks at a pair of American Wigeon sunning themselves on the far shore.

Further and further north we headed, passing what was obviously a few nesting Black-capped Chickadees, a White-breasted Nuthatch gathering food to take back to its own nest, and of course there was this Canada Goose nesting in one of the oldest trees in the park.

At the furthest point north in the park we did find a solitary American White Pelican, resting on the furthest north point of a large gravel bar, totally oblivious to the dozens of Franklin’s Gulls swirling around him.

On our way back south, we heard, and saw a pair of Cooper’s Hawks, I suspect ones that were either courting, or at least actively paired up and searching for a suitable place to nest in the area. We got many good looks at them both perched and in flight.

Along the way back south we also saw a lone Western Alpine butterfly. Probably not the first one of them I’ve ever seen, but the first one I’ve managed to actually figure out and identify on my own, so that was a treat!

Another of the birds that others were seeing all week was this Northern Flicker working on a nest cavity. Looks ready to move right in!

Just as I was packing up and getting ready to head home, this Red-tailed Hawk that we’d been seeing all morning began being harassed by a few American Crows, flying right over head. I’m always amazed that they don’t just bank around and snatch the harassers out of the air for a quick meal.

Have a great week, and good birding!
