Update on recent Red Kite deaths
At a time when we would hope to be bringing you news of the nesting season, we have sadly two updates on birds who died earlier on this year:
DEAD RED KITE FOUND NEAR ELDWICK, WEST YORKSHIRE, ON 19/03/18
This bird was found dead on a bridleway by a field studies group. The testing of samples from it have shown that its death was most likely due to the ingestion of rat poison. The findings indicate that there were traces of three different rat poisons in its system, suggesting that it had fed on dead rats which had been poisoned in the course of legal pest control. Background levels of the three substances brodifacoum, bromadiolone and difenacoum feature regularly in kites tested for suspected poisoning. However, in this case, the level of the brodifacoum findings were higher than usual and may have significantly contributed to the bird’s death.
Such deaths are referred to as secondary poisoning, reflecting the indirect means by which the death has been caused. However, whilst there is no suggestion of a human element having been involved in deliberately causing the death of the bird, it is a requirement that users of rat poison should employ good housekeeping techniques to ensure that regular searches for the bodies of rats poisoned by this means are undertaken. They should be disposed of by safe means to prevent them getting into the food chain of species such as Red Kites and Barn Owls. This is in addition to the moral obligation placed on users of poisons to minimise any adverse incidental effects which they may have on wildlife and the natural environment.
This is the thirteenth confirmed rodenticide related death of a Yorkshire Red Kite since releases began in 1999.
INJURED RED KITE FOUND AT HAREWOOD, WEST YORKSHIRE, ON 10/05/18
This bird was found by two walkers on a public right of way on Harewood Estate. It was retrieved and taken for veterinary examination. It was found to have a badly shattered right wing. Its injury was so severe that it was put to sleep. X-ray examination revealed a piece of lead lodged in the elbow joint. The humerus was detached adjacent to the joint, having apparently been hit by another piece of lead.
The injured bird was found close to the northern boundary of Harewood Estate, near the junction of the A61 and A659 at the bottom of Harewood Bank. West Yorkshire Police launched an appeal for information about the incident, but none has been forthcoming.
