Goldcrests are found in Ireland all year, but large numbers of them migrate into and out of Ireland each year in spring and autumn. The largest numbers of them arrive in autumn to escape the extremely cold continental winter temperatures of Scandinavia and Siberia. I tool this video last week showing a goldcrest looking for small insects in the leaves of a cotoneaster tree. The best views of this handsome but tiny bird can be seen in the second half of the video.
As many people undoubtedly know, Ireland has very strange weather even at the best of times. Winter snows rarely last more than a week or two if they come at all, and summers can be incredibly variable. The Irish climate can best be described as mercurial, but for the most part it is consistently mild. Last week and the week before it we had some bouts of very warm weather with temperatures reaching 17 degrees Celsius on Halloween itself, largely due to a warm tropical wind from the south.
This wind had control of the temperatures earlier in the week too, and prevented many migrants from flying south. Most notably Scandinavian Swallows and House Martins were forced east to forage in our warmer climes and I was amazed to be photoographing them in large numbers swooping overhead, although my shots were not great in the autumn light, nevertheless you can see them here.
And equally astounding have been the sightings of Red Admiral butterflies feeding on late-flowering buddleia bushes. But I have seen these butterflies in November in other years, prior to cold snaps.
They are now known to hibernate in Europe if the occasion demands it. There is even some evidence these migrants have successfully bred here in milder winters. However, temperatures have already dropped within the last few days and the skies already belong to the talkative Starlings who are amassing in huge numbers and flying in great ‘murmurations’ in a display of incredible aerial agility. They are lovely birds, and they enjoy the sun when they can get it in Wicklow winters.
Traditionally yesterday, November 1st – All Saints Day, marked the beginning of the Celtic Winter, which ends on St. Brigid’s Day – February 1st. However, from a practical point of view this time of year is deep Autumn.
