At the table

  • eggs and chicks of other birds
  • anything bright and shiny

A thief by reputation: eggs, chicks and other birds' nests are all targets, and anything bright and shiny gets a jackdaw's attention. They have even plucked wool from sheep's backs to line their nests.

What to know about the jackdaw

Eight short notes in our own words. Each chip says what the note stands on, and links to its row in the table below.

The jackdaw part of “British Birds in your Garden” by The Great British Channel, 7:47 to 9:17. Press play and it runs in YouTube's own player, with its captions and controls. Nothing from YouTube loads until you do, and after that YouTube can see your address. Watch it on YouTube instead.

What to look for

Much smaller than a crow or a rook, with a pale grey nape that stands out against otherwise black plumage. The eyes are strikingly pale.

Male and female

The video does not say whether male and female jackdaws look different.

not in the video

The young

The video does not describe young jackdaws. BTO says an adult's eye is a piercing silver-yellow, and a young bird's is blue.

BTO only

Song and call

A distinctive call, easy to tell from a crow's or a rook's. The video does not describe the sound. BTO writes it as a chack-chack.

BTO only video only

Nest

Jackdaws breed in colonies where nest sites are plentiful, in holes that can be natural, such as a tree, or man-made. Church spires seem to have particular appeal.

Feeding

A thief by reputation: eggs, chicks and other birds' nests are all targets, and anything bright and shiny gets a jackdaw's attention. They have even plucked wool from sheep's backs to line their nests.

Staying or leaving

Rapidly spreading its range through Britain, and there are few areas without a nearby population. BTO calls it a resident, topped up in winter by birds from northern Europe.

In the garden

Despite being one of the so-called baddies of the bird world, jackdaws are fascinating to watch, with exuberant flying displays that can be spectacular.
