Mars And Venus

Saturday morning and at 5am the alarm buzzed in my ear. Fifteen minutes later I was washed, dressed and had made a flask of coffee for the 40 minute journey to meet Andy at Oakenclough. 

By six there was zero wind and a few spots of rain. The rain was nothing to worry about as it quickly petered out and left perfect conditions for ringing. Once gain the ringing was very subdued with nothing in the way of migrants as the weather south of here continues to block migration. 

We ringed just 14 birds of 4 species - 8 Goldfinch, 3 Chaffinch, 2 Coal Tit, 1 Robin. For this time of year it is quite unusual that we caught zero Lesser Redpoll or Siskin today. Even the two Siskins we saw were probably fairly local wintering birds. 

The male symbol ♂ is the astrological symbol for Mars and the female symbol ♀ is the astrological symbol for Venus. Of the three small finches it’s the Goldfinch that is the harder to sex. While male and female Redpolls and male and female Siskins are quite different in their respective looks, the distinction between boy and girl Goldfinches is less obvious. 

To decide ♂ or ♀ Goldfinch we use the amount and shape of the patch of red feathering above and behind the eye combined with the colour of the nasal hairs. Wing length is an additional aid to sexing with a boy wing mostly longer than the girl equivalent, despite some mid-range overlap. The often slightly larger overall dimensions of a male can carry over to the bill whereby the bill of a larger male can be strikingly long. 

None of the above methods are of much use in the field and certainly not in the autumn with moulting adults or brown juveniles that lack any head colouration.

A local person we saw this morning today told of two regular Siskins on his own garden feeders. He knows of a nearby bird enthusiast and a garden well stocked with feeders that holds many more Siskins, Chaffinches and even a handful of Bramblings. The latter species has been very scarce during this Lancashire winter.

Apart from the ubiquitous Goldfinch The best I can do in my own garden at the moment is a couple of wary Tree Sparrows that come to snatch a few grains of millet and an equally shy Stock Dove.
