Yesterday evening while on a walk, around 6:00 pm I saw a small falcon land atop a very tall conifer in White Rock some distance away. There were some high-pitched sounds coming from the general direction of the bird but I dismissed it as gulls, thinking the falcon's there just surveying the area for a meal, and continued on the walk. Not having binoculars or a camera, I only noted the silhouette in flight, which had long and very pointy wings. Then on the way back about a half hour later, I encountered it again, on a different tall conifer (again perched right at the top), but this time I noticed it was calling. It then flew north another 100m or so to yet another conifer's treetop, and I noticed the long thin flat-ended tail. Overall size very small (smaller than a pigeon). I made a recording of the call, attached here. This sounds like a Merlin, and I wonder what it was trying to say, e.g. territory marking, calling out for a mate, something else?
