The kestrel
What birds of prey can be seen in Scotland: the kestrel
Although Scotland is perhaps most famous - especially amongst falconers - for its peregrine falcon, it may surprise you to know that Scotland is home to more than 20 varieties of bird of prey. In this series of posts, we'll introduce you to some of the birds of prey that you can see across Scotland.
The Kestrel
The kestrel, whose Latin name is Falco Tinnunculus, is one of Scotland's smallest birds of prey. As with all raptors, the female is larger than the male, but kestrels are typically not much bigger than blackbirds and weigh only 150-250g/5-7.5oz.
A russet-coloured bird with long, dark tail feathers, the kestrel is often seen along roadsides and motorway verges, where you can watch them fly in their characteristic hover pose. This is a classic 'waiting on' technique that kestrels use to 'read' the ground below them as they hunt for voles and mice.
Hunting technique
As well as the hover, and having the excellent eye sight typical of all falcons, kestrels also have another very special hunting technique: they can see near ultra-violet light. This means that in daylight they can see urine trails left by small mammals, following them even when the mice or voles are hidden in longer grasses. The kestrel can then pounce, swooping down from a height of about 15 metres, to ambush their prey.
Kestrel numbers
There are thought to be around 50,000 breeding pairs of kestrels in the UK but there is concern that numbers have been in decline in Scotland since the 1990s. This doesn't seem to be due to any one particular cause. It may be connected to increased traffic or changes in farming practices, or even to the success of the buzzard (a rival for its prey and also, on occasion, its predator), but more research into this is needed for us to be sure.
When and where and how to see kestrels in Scotland:
Throughout the year but choose drier, calmer days to try to see them.
Dainty, buoyant and fascinating to watch, this is a bird of the open countryside, across Scotland.
You're most likely to spot kestrels floating in the hover, seemingly stationary, close to roadsides.
