    Comments: As I was walking along the south side of the SW sewage pond I noticed a strange, loud call which was unfamiliar to me coming from the cottonwoods – it sounded raptor-like and I was interested to see what it was, but wanted to scan for shorebirds first. However, there were only a few Long-billed Dowitchers and peeps present, and I soon saw why – a juvenile Peregrine was hunting over the area, mainly along the fence line near the cottonwoods; it was small-bodied, presumably a male bird.

    The Peregrine occasionally appeared to be diving on something perched high in the cottonwoods. As I was following the Peregrine through binoculars suddenly a similar-sized and –shaped bird came rapidly into my field of view, tangled with the Peregrine at about half the tree height level, turning upside down and almost locking talons with the Peregrine; at this point I saw a flash of bright white somewhere on the mystery bird. The bird quickly righted itself and flew directly away from me into the large cottonwoods and out of sight. It was probably a bit smaller than the Peregrine. I was able to see that the wings were slim, pointed and seemed uniformly light pearly gray above. The morning light was to my back, so I was confident of the colours I saw. White-tailed Kite came immediately to mind – it was much too small for a male Northern Harrier, did not have black wingtips and was the wrong shape. I did not notice black shoulder patches, but as the bird was against dark trees and flying away from me these would not have stood out from the background as much as the overall wing colour. I walked towards the trees, scanning, but saw nothing perched there. The calls started again, but then became fainter – the calling bird was leaving, but on the other side of the tree line and not visible to me.

    At this point I checked the sound of White-tailed Kite on the "iBird Plus" app on my iPhone. The recording there closely matched what I had been hearing over the previous several minutes. This was a loud, chirpy call a bit like that of an Osprey, but sharper and shorter, given in a short series or persistently, with calls a second or so apart.
