Eye on nature

We were thrilled to see 15 red squirrels in Beleek Woods, Ballina – a triumph for their reintroduction. Do they not hibernate?

Barbara Browne, Ballina, Co Mayo

Neither red nor grey squirrels hibernate, but they are less active on the coldest days in winter.

Do birds eat snow if water supplies are frozen?

Edwina Clerkin, Clonskeagh, Dublin

They do, but it takes a lot of energy to melt it inside their bodies. Better to put out water several times a day for them in icy weather.

I was surprised to see a badger cross Knocklyon Road and go into a hedge. What an unexpected encounter with such a reclusive creature in Dublin suburbia.

Brian Johnston, Knocklyon, Dublin

It probably lives in a nearby park or on a riverbank.

A bullfinch has been pecking at the branches of my Japanese plum tree. What kind of food is so attractive to it?

Pat Maher, Greystones, Co Dublin

Bullfinches usually feed on insects, berries, seeds and buds. It is probably stripping the buds from your tree. We’ve had several reports of snipe foraging in gardens during the snow and frost.
