After a deluge that passed over us, it always goes back the same way!
I'm talking about normal weather patterns, after a storm passes through south-west Andalucia, the sun kicks back in and we have clear sunny skies again. The only difference is that the current rainfall has been much greater in volume than in the past. An effect of global warming I should imagine.
But where most people notice these obvious greater effects, with flooding then drought, wet summers and mild winters, the birds and animals change and adapt by the way they live their lives just as we do. A warmer climate in Europe will keep on attracting more exotic southern birds for example, to spread northwards from their 'usual' territories, as food becomes more available in these traditionally cooler northern areas. Recent arrivals in Europe from Africa that are now breedinginclude Black shouldered Kites, Slender-billed Gulls and Western Reef Herons (breeding with Cattle Egrets resulting in hybrids). Rüppell's Griffon Vultures are now regular visitors and some stay on in the south for long periods. Just like Lanner Falcons and Atlas Long-legged Buzzards it will only be a matter of time before we'll have locally breeding birds.
The effects of our warmer climate means that there is a whole world of change taking place beneath our feet that goes practically unnoticed.
Looking at the amount of Red Signal Crayfish that are being eaten by Storks, Herons and Ibis in the La Janda rice fields, it seems that this species which was introduced in the late 1950's - early 1960's, has had a very prolific breeding time and now is one of the reasons coupled with the milder winter weather, that both White and Black Storks can survive here in Andalucia without having to undertake the great journey south to equatorial Africa. The result of not having to do this often hazardour journey each year means less numbers die and results in increased population amongst this particular species. The equation of ample food source and better climatic conditions outwith breeding times can also be used with the tremendous population explosion of another bird species the Glossy Ibis. Not such a long time ago, Glossy Ibis would have been a rare bird indeed in Europe. In the last fifteen years the breeding population has risen from single figures to in the thousands. Quite a remarkable success story. Since the darainage of natural wetlands in both Huelva and Cadiz provinces for rice production, the dramatic loss of habitat for many species meant a reduction of numbers and I presume the loss of specific species like Marsh Owl, Crakes and Rails. (Sadly there isn't enough information available on specific recordings or population density or distribution in this area for the 1950's to the 1970's.) The Glossy Ibis was a bird species that did profit from a combination of re-introduction/breeding programmes and the availability of new food sources in and around the agricultural areas.
Sacred Ibis are already in the Doñana parks and I suspect that unless some group activly stops them, they'll be breeding there too! These birds are either escapees from collections or from an already established group in Brittany, France.
Other larger and of course more noticeable escapees include Chilean and Lesser Flamingoes, Ruddy Shellduck, Cape Teal, Egyptian Goose, White Pelican and Black Swans.
Smaller caged-birds were released in their thousands in Spain and Portugal when the news that avian flu was going to be of 1919 proportions. The panicing owners released some quite exotic and stunningly beautiful species into the countryside. May of course din't make the assimilation from being cared for to abandonment. Others have successfully started small colonies or populations down this way and some like the various populations in mant Iberian cities the Monk Parakeet. Red Avadavat and Common Waxbill are even accepted as being 'Spanish' birds or even listed on the official list of birds of the Western Palearctic. What an accolade! Bouquets of Laurels, palms and bays say the birds....
