Well it didn't take long - just my third visit to Brent this year and I failed to add a yeartick. Without anything moving there wasn't much prospect really. I counted all the Teal - 182 which I think is a new site record. Also took a 'walk' through the jungle of East Marsh, the path in front of the factories has long overgrown, disappeared, got blocked by fallen trees, crossed by pollution spills etc. There was a chance of Chiffchaff and I did hear a sinle call which could have been but didn't see anything.
I won't have much time to add anything else now for the rest of the week as I'll be at work. Still got to pop up at dusk and listen for owls.
