Lodge Lake yesterday morning

I've been asked to carry out some urban bird survey's for a local ecologists. Yesterday was my first at Lodge Lake. Nothing earth shattering as this was the initial "what's actually there" survey. Highlights were a male Sparrow Hawk whizzing through with a couple of Greenfinch as his wing men. But the best surprise was a female Goosander which circled my position and appeared to land on the main lake, out of my view. Around 5 minutes later the bird circled above again and flew off towards CMK. (Disappointingly this being my second visit in a week and still no sign of the normally regular Little Grebes!)
