This weekend's Friends of Fish Creek Park outing headed to South Glenmore Park, where our focus was on songbirds. We were particularly interested in locating a hybrid Rose-breasted x Black-headed Grosbeak that had been sighted in the area. The clouds cleared by the end of our morning and we spent about three hours traipsing through the forest in the near constant company of Least Flycatchers, Yellow Warblers, and Red-eyed Vireos loudly marking out their territories.
On my way to meet the group, I stopped by the sailing club on the south edge of the reservoir. The water level is still very low as the city prepares for forecasted high river levels. There were hundreds of gulls, predominantly
Franklin's Gulls, along with
Ring-billed, feeding on the mud as well as
Great Blue Herons and the usual selection of waterfowl. I snapped this terrible digiscoped image to give you a sense of what this all looked like - imagine another 3 frames of the same stitched on the left hand side of the image:
Once we started walking, a Least Flycatcher was among the first birds to give good views to all participants. I think it was somewhat frustrating for some novice birders to locate such a drab bird in the dark understory but once we were all on the little flycatcher he put on a good show feeding and calling loudly.

We walked on through the forest and heard
Veery singing from the bushes. A new species for me but definitely on the "BVD" (better view desired!) list. Here's a recording of the song from xeno-canto. Our leaders for the outing gave two descriptions of the call which seemed to me a very accurate characterization - the song sounds like the bird is "winding down" and "singing from the bottom of a rain barrel". You can actually see the winding down part in the sonogram.
Eventually we reached an overlook with well stocked bird feeders. These attracted
Pine Siskins,
White-breasted Nuthatch,
American Goldfinch,
Brown-headed Cowbird,
Clay-coloured Sparrow, and another visitor which you will see below. Here are a few photos taken at the feeders before we returned by the same route.

But what about that Grosbeak? We had seen nothing and heard little by the time we made it back to the parking lot but two of the group had taken a slight detour and found the bird singing right beside the main bike pathway. Once I heard this I went back by myself and soon heard the bird in the spot they had described. Rose-breasted Grosbeaks sound like "Robins in a hurry":
However, in a moment of classic birding frustration, despite the continuous singing within 30 feet of my face, I could not see the source of this distinctive song. So, in conclusion, did we find the elusive hybrid? Fourteen birders did not, two saw the bird as clear as day, and one (I) heard a Grosbeak right in front of me, grudgingly checked it off my list, and want to return for another look soon.
