Busy Nanjizal week and more Skylarks

The last five days have seen daily ringing at Nanjizal, with 493 birds ringed, including 171 Blackcap, 74 Chiffchaff, 22 Firecrest (60 ringed so far this autumn), three more Yellow-browed Warblers (15 so far this month!) and a Little Bunting (one of two present). Also of note were late Reed Warbler, Garden Warbler and the six Siskin (unusual for the site).

Away from the Penwith valley, the rest of us headed out to Predannack (National Trust farm near Mullion) this morning to try for our first Skylarks of the winter. The fields were pretty quiet, so it's perhaps a bit early in the season, and pre-dawn drag-netting saw three birds slip under the net. We were slightly more successful mist-netting, though nine nets did still only produce four birds!

A rather grainy dawn photo, but the colour difference in these birds is hopefully still apparent,

While we were there we took the opportunity to turn the 'Skylark H' into a 'mipit triangle', but the presence of various raptors kept the majority of birds away from the nets. Some hedgerow nets did catch a single Linnet, in amongst a plethora of Dunnocks...

This bird was an interesting aside though, as it had hints of pinky-colour coming through on the breast (suggesting a male), but an incredibly dull, grey head. So we might presume that this was a winter-plumage male, but the moulting wing, and in particular the worn state of the unmoulted inner secondaries (and very dull head), suggested this was an adult part-way through moult. So quite why an adult male Linnet would look quite so shabby is a mystery, but we presume this is a second-year bird, having had a dull first-summer plumage and, so far, a delayed moult of its head feathers.

Note the newly-growing outer primary and the wear on the unmoulted inner secondaries

Helston gulls and our first Skylarks

After putting up a new Barn Owl box with the National Trust yesterday, I couldn't resist stopping off with a loaf of bread at Helston Boating Lake to see what gulls were around. I soon had a good gathering of Black-headed Gulls, along with a few other scroungers. The few birds there included the regular White 23D8 from Berkshire, but also a young Herring Gull with a nice blue ring!

W:047 was ringed on an industrial estate roof in Falmouth in June. This is only 15km from Falmouth, but still interesting to see it leaving the town rather than hovering round eating chips.

Later in the afternoon we then set nets out at Predannack in the hope of catching some of the 100+ Skylark using the set-aside fields there. Setting up seven nets in an 'H' pattern, we put a 'tape' on pre-dawn and at first light walked the adjacent field, moving over 30 birds towards the nets. But with a little too much dawn light, we only managed to catch eight birds, but now know better for next time (tomorrow). These are the first Skylark ringed by the group and weighing in at almost 40g some were quite impressive!

Swithching the 'tape' (actually an MP3 player) to Meadow Pipit, which seem to be less wary of nets in daylight, we topped up the day's catch with 16 Meadow Pipits.

Bit hard to see, but the 'H' of nets now furled for tomorrow morning
