Jay

 

Jay (Garrulus glandarius)

Jays are beautiful, colourful members of the crow family. Though they are widespread in UK woodlands, apart from Northern Scotland, they are quite shy and rarely visit gardens. We have been fortunate through the years to see them, usually in October, when they are foraging for food, particularly acorns. They cache their finds to provide food in leaner times, but do not always return for them, and that is how oak saplings can be found in unexpected places.

The rapid spread of oaks after the last Ice Age is attributed to this caching habit. Before oak trees were planted commercially, jays were the main means of distribution. A single bird might spread more than a thousand acorns annually.

The last Ice Age, known as the Last Glacial Period, began about 100,000 years ago.

In addition to acorns, jays eat insects, seeds and occasionally small mammals, nestlings, and eggs. They have unmusical voices but are clever mimics, copying the songs of other birds and common noises in the environment, like dripping taps, or people whistling.

  1. I grew up in Indiana with blue jays (cyanocitta cristata) and am now daily entertained by our ubiquitous Steller's jays (cyanocitta stelleri). Your jay pictured is quite different and strikingly beautiful. I suspect the term "garrulous" befits all three jays.

    1. to look at but seem to share many of the same characteristics. As they're all corvids, that's not surprising. Birds are so entertaining.

    2. The first part of my reply went astray! I was saying that your blue jays look very different.

  2. I meant to add that the Steller's jay lives in the western US.

    1. Steller's jay has a prominent crest that makes it look quite surprised. 😃

  3. Handsome creature.
    I have never heard of a brown, black and white bird with a small, perfect strip of navy and white feathers on each side.

  4. I've seen several types of jays in my travels, but never knew about their propensity for burying acorns.

    1. It's surprising how many birds cache food.

    1. Thank you for the link, Debby. The beautiful blues are almost electric in their vividness.

    2. They are loud and bossy, and like to yell a lot.

  6. I knew Jays were part of the crow family but didn't know they are so pretty. I shall thank them virtually for the spread of oaks, one of my favourite trees. We don't have Jays in Australia.

    1. Thank goodness no-one imported them to Australia. Most introduced species do more harm than good.

  7. Pretty birds. You're right we don't see jays in Northern Scotland. I wonder why. Colder weather? Lacking the right habitats?

    1. Apparently, it's a combination of climate and habitat. Jays prefer foraging in forests and are not suited to the open heath and moorlands.

  8. They are a lovely looking bird, and they mimic like our lyre birds. And, they are from the crow family, so I suppose corvids.

    1. Lyre birds are extraordinary, the males with their flamboyant tails, and their mimicry skills.

  9. We had jays in our garden down in Sussex but have not seen any since we moved up here. They are attractive birds.

  10. We saw our first ever jay at Kew Gardens the other week. One of our highlights of the day. (It was caching something.)

  11. I do like Kew Gardens, an oasis in the suburbs.

  12. Your jays are certainly not of the same personality is ours. Ours are more blue and they have a black ring around their neck. And not only are they allowed but they are extremely pushy about stealing food from the songbirds. I do love to see them but they can be rather aggressive. Yours is quite lovely looking. Of course I love all birds no matter what they're like.

    1. They certainly are the less forthcoming of the corvids.

  13. We had a Jay visit our garden last week. It is always a thrill to see them.

  14. We occasionally see one in our suburban garden. Are they your own photos ma'am? Really good.

    1. Yes, they are our own photos from a few years ago. I can't take the credit, though. Barry takes them and I merely catalogue them.

    2. Not so far as I'm aware, though he did have some excellent secretaries/personal assistants. I'm *just* his wife. I don't think he's a bigamist, though I know he was offered a couple of wives . . . I was never offered a couple of husbands . . .

  15. I didn't know about the Jays caching acorns, that would explain the random oak saplings in our garden.
    I rather like them even though I know they can be aggressive towards other birds.

  16. It's incredible to think that such a shy bird could be responsible for so much of the landscape we see today. Also, I had no idea jays were such skilled mimics! A fascinating post!

  17. Interesting. We have a type of Jay, Bluejay. They are a brilliant shade of blue. Loud and bossy around the bird feeder - CJ

  18. Lovely bird. Their diet has much in common with our Blue Jays, although their personalities seem to be quite opposite.

  21. Lovely photographs of this attractive bird.
    There was great excitement last year as we had two who visited, unfortunately not seen them this year!

    Many thanks to Barry for the photographs and to you for cataloguing them.

    All the best Jan

  22. We have one type of jay in the Northeast United States where I live - the blue jay (Cyanocitta cristata). Both male and female are - well, mainly blue. I had never seen a picture of your Eurasian Jay and it's so different in looks but probably just as enjoyable to see. (Ours can be bullies at feeders, though. They don't like our small yard and I'm glad for it).

    1. Our jay is not very bold at all, unlike his corvid cousins.

  23. We have blue jays here in Wisconsin. I suppose they are related in some way to the jays you wrote about, but they don't bear any resemblance that I can see.
