At the table
- peanuts
- aphids, caterpillars and grubs
A feathered gymnast that tries every possible food source, and clever with it. At a bird table, peanuts are a particular favourite. For organic gardeners it is a must: it scoops up aphids, caterpillars and grubs to feed its young.
This page mentions bird tables. Since April 2026 the RSPB and the BTO advise against them, and say to feed seeds and peanuts only from November to April. What changed, and why.
Through the year
Blue tit: around Jan to Dec; noisy young parties leave the nest, Jun to Aug; small roving bands in winter, Dec to Feb; first eggs laid 12 Apr to 11 May, average 26 Apr (BTO); first chicks leave the nest 13 May to 15 Jun (worked out from BTO).

What to look for
One of the best known and most popular garden birds, and easy to recognise: blue and yellow plumage, and a small, compact shape.
Male and female
The video does not compare the sexes. BTO says they are similar, with males slightly brighter on average.
The young
Noisy parties of young blue tits come out of the nest right through the summer, which is a delight to watch.
Song and call

Nest
Offer a nest box with a whole-front opening, the kind with a hole in the front, and blue tits will use it.
Feeding
A feathered gymnast that tries every possible food source, and clever with it. At a bird table, peanuts are a particular favourite. For organic gardeners it is a must: it scoops up aphids, caterpillars and grubs to feed its young.
Staying or leaving
In winter, blue tits often form small roving bands that look for food together with other birds their own size. Widespread, but it avoids inner-city areas, where sightings are much less frequent. BTO calls it a common resident.
