Swift on the wing © John N Murphy
Spring seems like a lifetime ago. The end of May was the last prolonged
spell of fine weather we received from the gods, and it now feels like it was
our summer. Way back then we
welcomed the long summer evenings that were rapidly approaching and people
looked forward to warm days and the return of the Cuckoo and Swallow. Both species are supposidly a natural
indicator that summer has officially arrived. How wrong we were, we are still
awaiting the summer, one that we now hope will be an Indian summer and it might
arrive in late August or September.
Now that we have come close to the end of our summer and Autumn is in the
air, we were not the only ones wishing and hoping for fine weather. Spare a thought for the poor little
Common Swift. The Swift is an all
brown or black large looking Swallow like bird, that returns from south of the
Sahara at the end of April or the first week of May every year. This year he must have though,
fantastic, great to be home again in Ireland. This basking sunshine is just what I need, a good year for
me to catch loads of flying insects and raise a large Irish family. How wrong he was also.
Swifts live a fascinating life.
Since humans have been building tall structures like castle and round
towers, Swifts have been nesting in them.
They departed their caves and cliff face dwellings to raise young in a
vast array of manmade structures. In some parts of eastern Europe, Swifts still nest in holes high up in tall trees. Nowadays one of their favourite spots to nest are high up in Cathederal
Spires, old tall Mill buildings and in the attic space of any tall house or
structure. Here they will not
actually build a nest but lay a couple of eggs on a beam of on some ceiling
plaster board or insulation.
Swifts have long wings and short legs so they never land on the ground. If they do, they cannot take off again
without assistance. Swifts spend
all their time on the wing, high in the sky. They sleep on the wing and coppulate on the wing also. One of the few wild birds that are
members of the mile high club.
But they are under serious treat.
The last four summers have seen very wet, cold and unsettled weather patterns creeping into June and
July. These conditions do not
favour the Swift. Issues they face
are the loss of nest sites through the demolition of old buildings. The lack of
insects at high altitudes due to low pressure and moist conditions in summer, a
factor and trend now accepted in our summers. Torrential downpours are regular and heavy rain showers can
ground Swifts. These grounded birds fall fowl to cats, dogs, foxes and others. Swifts have been found to abandon nests
in June and July, returning to Africa earlier than their norm in the first week
of August because of these wet conditions. So for a species that traditional was the last to arrive
back from Africa, months and weeks later than the Swallow, House Martin and
Cuckoo, it is now leaving even earlier than than ever before, being the first
migrant out of the country every year.
A good book to read on the life of the Common Swift, is "Swifts in a Tower" by David Lack. It is hard to come by but one of the earliest studies carried out into the world of the Swift.
