Wheats About?

A wander out Pilling way on Sunday saw activity of mainly egrets, pipits and Linnets along the sea wall. Two identical looking Wheatears caught my eye so I stopped for a closer inspection.

The tidal defences here keep Morecambe Bay tides at bay with a high raised earth bank, (a bund) interspersed with sections consisting of large rocks and stones. The rockery is an attraction to migrant birds where crevices and holes out of prevailing winds provide a sanctuary to insects attractive to Wheatears and other insectivores. 

Over many years I have ringed over seventy Wheatears along Pilling shore, until taking a break in recent years when human and canine disturbance made the job impossible. Having recently found a new private spot, and even in the limited possibilities of September when their numbers decline,  the desire to catch Wheatears resurfaced with the appearance of these two Wheatears. I suspect the two were siblings so closely did they resemble each other and to follow in each other’s movements. 

Luckily mealworms were at hand together with a couple of spring traps that caught one bird quite easily as the other scooted into the distance upon seeing its companion compromised inside a tent of netting.

After a few days off I met up with Will and Andy on Thursday at 0630 for a go at the Linnets and anything else linked to the month of September. Thirteen birds caught/ringed -  6 Linnet, 5 Meadow Pipit, 1 Goldfinch, 1 Robin. 

We have to remind ourselves that male Linnets are normally a touch larger than females but this is never the decider between male or female. The most reliable method is the amount of white on the outer web of the primary wing feathers numbers 7 to 9.  A gap of less than 5mm from the white feather to the centre shaft tells us the bird is a male, more than 5mm a female. In other words, males have more white in the wing, a feature that is sometimes discernible with Linnets in flight, more easily picked out ina large flock rather than isolated birds.

Very often autumn males show brown/rufous rounded markings on the breast, unlike a female which is more streaked.

It is not surprising that about 80/90 % of autumn Meadow Pipits we catch are first summer/juveniles as the species is able to raise two broods of youngsters in a normal summer. The juvenile below is already part way through its post-juvenile moult.

Other birds seen and not caught - 50+ Linnet, 50+ Meadow Pipit, 8/10 Tree Sparrow, 2 Blackbird, 1 Kingfisher, 1 Marsh Harrier, 1 Peregrine overhead.

Fifteen Pink-footed Geese arrived from the north and landed on the salt marsh. The first of the Autumn.

Log in again soon everyone.
