Climate Change

The Great Tit(Parus major)

)L

In the 1960s, when sparrowhawk numbers had been decimated by pesticide poisoning, the most dominant great tits were also the heaviest. However, these fatter birds are the most vulnerable to sparrowhawks, so once the latter's population recovered, the dominant males lost their excess weight.

"Evolutionary biologists have known for some time that as the climate shifts it appears to lead to evolutionary change – some species go extinct, others come online"(Coulson) Due to global warming the great Tit’s biological connect to nature has been disrupted, with this warmer weather other organisms and plants blossom earlier then and the later hatching Tit’s miss out on this abundance of food and miss out, resulting in fewer surviving offspring. This is also given the offspring born sooner a much bigger selective advantage, studies have shown that the Tit’s are producing offspring 2 weeks earlier than they did in 1970. The Tit’s have also been able to adapt to warmer climates faster. Even with all these fast changing adaptions among the Tit’s there is still a 60% chance that they will go extinct.

Strange Behaviour

Some Tit’s have acquired a taste for bats. In some Hungarian caves the great Tit’s heard the bat calls and then proceeded into the caves where they feed on the bats inhabiting the cave. This is some never before seen behaviour seen in the Great Tit’s. The European Tit’s have also been caught killing robins in a similar, pecking through the skull. Some of scientists this is a reaction from the mothers of offspring that have missed the peak feeding. Other scientists think the Tit’s are just hunting closer to their nests. However most scientists agree that the climate change has sparked a change in the Tit’s behaviour.
