Well folks, it's was definitely a 'wash-out' today. I saw absolutely no birds...from my kitchen window! We'll try again tomorrow.
At present, the predicted forecast from wunderground.com is "Overcast in the morning, then mostly cloudy. High of 15C. Breezy. Winds from the NNW at 15 to 25 km/h". And from theweathernetwork.com "NW 20 km/h wind switching to N 20 km/h, with gusts up to 30 km/h". Sounds to me like a beautiful day to be at the park hawk-watching!
