Buzz-off

There was an excited call from my wife the other day when she spotted from our upstairs skylight a large bird in our neighbour’s garden. It turned out to be a Buzzard (Buteo buteo) standing slightly hunched and initially motionless in the grass. After a while it walked slowly to perch on a bench. On closer inspection with the neighbour it seemed unwilling or unable to fly even in the presence of two sizable Tom cats. Sadly a few hours later it died.

So what could have been the cause of death? My immediate thought was that it had hit the ground too hard whilst chasing prey or had taken a glancing blow from a car on the nearby A road, before coming to rest in the garden. However a friend informed me that there would appear to be a lot of poisoning of birds of prey occurring in Devon. There are certainly a lot of young pheasants to protect in our area and an over-zealous gamekeeper might be tempted to break the law. This is supported by the RSPB’s latest Birdcrime Report (RSPB, 2012), which shows Devon to be one of the worst areas in the UK for confirmed persecution of birds of prey. On this basis I rang the 'Predatory Bird Monitoring Scheme' (PBMS), who take in suspected cases of poisoning for analysis. However the chap I spoke to felt our Buzzard’s was more likely to be the result of injuries from a collision that had enabled the bird to initially fly away but later suffer from internal bleeding. He said this was supported by a number of specimens that had been sent into them and that without circumstantial evidence it would be hard to prove anything.

This is clearly an awful tragedy for the individual bird and we will never know now what caused its death. However the backdrop is of a bird species that has been very successful over recent years expanding into/returning to many areas of Britain. We appear to have a very strong local population and are lucky to have daily experiences of them perched or soaring over the landscape.

Bonky tit!

It’s been a difficult few weeks. Each day around dawn a fluttering and scratching begins against the bedroom window continuing throughout the day. The giant moth-like muted sounds are strangely able to pierce sleep and their irregularity ensures no sustained slumber. It all started over two weeks ago at a different window - The Magnolia branch outside the annexe building provided a convenient platform for a Blue Tit (Parus caeruleus) to seemingly launch an attack on its window reflection. At first we were amused and fascinated by the behaviour assuming that it was searching for spiders and other insects around the window frames. Friends staying in the annexe over following days were the first to suffer from the unwonted early alarm call, but we dismissed it as a passing ornithological whim. The pile of droppings beneath indicated a more zealous prolonged cause. What made it extend its attack on other fenestration foes can only be conjecture, but in the following days the kitchen and my bedroom windows fell under a sustained attack, reminiscent of scenes from Hitchcock’s ‘The Birds’. Finally, and perhaps more understandable, the car side-mirrors were drawn into the illusory battleground of this tiny two-winged bandit. The cumulative sleep deprivation rapidly induced less lovable inclinations to the blue fluff-ball! I began to ponder what I would do if I could get it in my hands. You will be pleased to know that a calmer wife has since found a solution, by covering the window with an externally hanging towel and taking away the bird’s attack trigger.

Apparently the size of an ostrich brain is the size of a pea. So how big can a Blue Tit’s be? How amazing that this tiny accumulation of nervous tissue can trigger such exaggerated behaviour, with such dramatic consequences on my life. The RSPB website (http://www.rspb.org.uk/) comments that “there is no apparent reason to what triggers an individual bird suddenly to start this behaviour, and it cannot be predicted how intense it will be and how long it will go on for.” Clearly we were at the start of the breeding season and I can only assume that this particular individual bird was shot with an unusual amount of hormones to fuel such a marathon assault.

Now I’m off for a nap!
