Black-headed gull, moorhen, mallard and Canada goose at Thornes Park duck pond this morning.
My Ode to a Duck animation is going to be a biodiversity hotspot: here are the latest recruits, the moorhen and coot. It’s surprising how these characters take on a life of their own: I’d never thought of a moorhen as being a bit of a spiv or of a coot being an ingenue.
2.30 p.m., 13ºC, 55ºF, blustery winds and continuous showers from the west: Forty or fifty black-headed gulls flock down when children scatter breadcrumbs by the semi-permanent puddle alongside the duck pond at Thornes Park. I spot only one gull with the full chocolate brown mask of its summer plumage; some have just a dark dot behind the eye, others are at a halfway stage.
I draw a gull in flight which has a black band at the end of its tail but when I look up again every gull has a pure white tail. I’m start to think that I must have been mistaken but I must have seen a juvenile which – so my field guide tells me – does have a black band at the end of its tail. The colour of the feet and of the bill also vary between adults and juveniles.
It’s such a dull rainy afternoon and I’m sheltering in the car putting the wipers on a occasionally so I’m not seeing the birds in glowing colour. I have to admit that the green of the drake mallard’s head is really informed guesswork. In this light, to me it just looks dark.
I wind down the window to get a better view of the moorhens which are poddling around the muddy margins of the puddle, picking up scraps.
Each bird has it’s distinctive way of getting across the canal;
The Moorhen has the most amphibious method, combining land, air and water for the short journey. As it sees us approach, it pauses on the towpath, stalks a few tentative steps to the bank, launches itself into the air with limited effect then staggers along the water surface for a few paces – with the out of control momentum of someone jumping onto the platform before the train has stopped – before settling to swim the last yard or so to the seclusion of the bankside vegetation.
The Wren zooms along, wings a-whir, from the undergrowth on the towpath side to the hedge on the far bank.
A small group of Long-tailed Tits take a roller-coaster flightpath from the tops branches at one side to those on the other. Repeated wing-beats interspersed with short rests result in their bouncing flight.
A pair of Mallards swim across with a surreptitious air. The drake might be trying to avoid the attention of rival males. Later we see a duck closely pursued by two drakes flying up river.
