Early Bird Catches the Snake
The British Trust for Ornithology often receives reports of birds eating unusual prey items, a recent record of a Blackbird taking a snake proved to be quite exceptional.
The snake, identified by the observer Christine Dancey as a young Grass Snake, was reported to the BTO Garden BirdWatch Team. It was seen to be coiled in the beak of the Blackbird, with the head and tongue clearly visible dangling from the beak. However, it wasn’t all plain sailing for the Blackbird – it had to defend its prize from a pair of Magpies that seemed intent on stealing its meal.
Mike Toms, BTO/CJ Garden BirdWatch Organiser commented ‘Although it may seem odd that a Blackbird should attempt to predate a snake, young Grass Snakes are surprisingly small and are not much thicker than a large worm. The snake would make a good meal for the Blackbird and it is possible that this choice of menu item is more widespread than we realise. We would love to hear from any other observers who have witnessed Blackbirds (or other species) taking snakes or small lizards.’
Last year, the BTO commented on Blackbirds taking newts, tadpoles and even small fish. This shows that they are adaptable when it comes to diet and this may be why they have done so well.
* The Blackbird, a member of the thrush family, is a common garden bird; the UK population is estimated at 4.9 million pairs. It has a varied diet, feeding mainly on earthworms, other invertebrates, soft fruits and berries.
* The Grass Snake has a largely southerly distribution within the UK and is often found close to water. Garden ponds are well used since this species hunts mainly amphibians. It is not poisonous. This particular incident took place in Suffolk.

USA: Clearing forests is generally bad news for many native animal species, including rat snakes, but a new study has found that rat snakes that manage to survive in fragmented forests do quite well — much to the detriment of the birds they prey on: here.
