Passing an old Ash tree along Broomham Lane, Catsfield (Sussex) today I heard some nestling birds calling for food so I waited and watched this pair of Great Tits carrying insects at frequent intervals into the hole in the trunk (and poo sacs out!.) Both male and female feed the young on protein-rich caterpillars, beetles, aphids and spiders. Later, when they have grown more, they will be able to introduce seeds to their diet as well. Great Tits are the most studied birds in the world, and will use nest-boxes in your garden. May and June are their busiest months, having an

The worry for this pair, and for other tree-nesting birds is that most of the mature Ash in these parts, including this one, are succumbing to Ash die-back. Though the tree will last a few years yet, where will future nest sites for Woodpeckers, Nuthatches and Tits come from when these valuable trees fall- unless we all put up more nest boxes, in gardens and woods. Conditions: Blue sky and gentle breeze. Temperature: Max 16 Min 5C.
