Jackdaws are the smallest crow found in the UK, growing to around 250 grams in weight and to have a wingspan of 70 centimetres. They are slate grey over most of their bodies but have a noticeable black cap and light blue-grey eyes.
They roost and feed in small communal groups and can often be seen foraging among other crow species such as rooks and carrion crows. As they are highly intelligent, jackdaws have an extremely varied diet which includes, fruits, vegetables, seeds, carrion and invertebrates but they are also renowned for taking eggs and chicks from other birds nests. With such a diverse menu, jackdaws can manage to eek out a living just as well in woodlands and farmlands as they do in towns or cities.
As well as roosting a feeding communally, they also nest in small groups. These nests would naturally be in tree hollows or cavities but in urban areas they are particularly fond of attics, church spires and chimney stacks. The nest are cup shaped and mainly made with twigs and then lined with hair or wool. Each females lays between 4 and 6 creamy blue speckled eggs that measure 3 and a half centimetres in length. These take 17 to 18 days to hatch and the first egg laid will be the first to emerge. This means that if there is not enough food for all of the growing chicks, the oldest will be strong enough to out compete their siblings and survive. In nature it is better to have 2 or 3 strong young than 5 or 6 weak ones. After they’ve hatched, both parents feed the young in the nest for about 4 and half weeks before they fledge. Just like most other corvids, once the young have fledged they stay with their family group for several more weeks being fed by the parents and learning how to find food for themselves.
Just like other members of the crow family, Jackdaws are extremely intelligent. They have been shown not only to be able to recognise people, but also the expressions on their faces. Within their social groups there is a hierarchical structure with unpaired females being the lowest ranked. However, this all changes when a female pairs up as she instantly assumes the rank of her mate and this is accepted by all the other birds in the flock. Even more to their social structure, Jackdaws have been shown to regularly form same sex pairs, especially if one of their previous mates have died prematurely.
Over the past 50 years, jackdaw numbers have been rising in the UK and there are approximately 3.2 million of them living here. In the wild they have an average lifespan of around 5 years although one that was captured in 2014 was ringed as an adult 17 years before. There have also been reports of captive birds living for as much as 30 years!

    I was lucky enough to raise and release a Jackdaw 2 years ago. 96% wild now but when he returns, he remembers me and my family and will come on our arms to feed still. It's an incredible feeling of trust and gratitude you gain from them in a way.
  • Jackdaws have been nesting in one of our chimney pots from before we moved in in 1975. They often have all their friends round for parties that always end in a fight, just like some humans :)

    Me and my father saved a jackdoor that was stuck in my parents farm house chimney for a few weeks, we had to smash the chimney out to get to it, we first thought it was nesting in there but realized it was stuck! we had to nurse it back to health for over a week, it was so ill and weak that day it was 50/50 weather it would live we was thinking, it was so tame and domesticated we thought as it carefully took the food and water from our hands, as if it new we wanted to help it, It would look at us in the eyes so friendly, as if it had lived with us all its life, never showed us any aggression, we let it go free once it started flapping in the cardboard box 📦 after its week of rest , it flew on to the roof we hoped it wouldn't go down the chimney again but it didn't, it stayed with us for the next 9 years! watching us from the roof or when we hung out washing it would swoop down onto the grass around 3 metres away and just watch us and dig for worms then when making breakfast it would come to the kitchen window we would put out a peace of buttered toast 😀 for its breakfast on the window ledge, it would get one every morning ! So intelligent and it understood we were friends or extended family in its mind? I'm so glad we knocked out the chimney to gain a life long friendship,watching this video has brought all the memories back for me, I thought we has a one off jackdaw but I now know their all special.

    I feed Jackdaws all year around. During the summer i supply them with fresh water and daily meals of oatmeal porage. There much enjoyment just sitting and looking at them while they do their social stuff. Love the Jackdaws, each their own personality.
  • Jackdaws are so cute, I wish we had them in the states. Interesting video thank you for sharing!
  • These guys are probably my favorite european bird. They're so inquisitive and frankly adorable
  • Your "Did You Know?" videos are always a treat Liam, and this one was no exception. Well chosen clips superbly narrated. Top work mate. 👍🙂👍

    I live on the 5th floor and love to sit out on my balcony in the warmer months and watch the big clouds of jackdaws return to the city to sleep. They often use my appartement building and the one next to mine to sort of regroup before heading off to sleep in the trees of this city. When I wait for the bus they sometimes come closer to me. But I don't look at them if they get to close as they know when they are being watched and I find that when I turn my gaze they relax a bit and might come even closer. Jackdaws are easily one of my absolute favorite birds.
  • i had a pair nesting in my loft, they pecked a perfect square on the facia board to get in. The nest was a work of art
  • Such beautiful birds. I often see them on the roof/chimney of the building opposite where I live, I'm always happy to see them 😊
  • @AndyAstbury
    3.2 Million, and half of 'em are on my feeders all day! Another fantastic video 👍
  • @mefjux6902
    Those little fuckers (affectionally, I love them) are so smart its amazing. I got like 8-9 species of birds where I live, obviously I feed them all but jacks seem to get that im a friend and whole feeding routine. Edit, Jacks are seriously like little humans but nicer and more civilized.
  • @grampawud
    We have a few jackdaws that nest in our unused chimney pots. I find it quite enjoyable watching them mucking about in the garden, rolling about and fighting.
  • I adore crows in general and Jackdaws in particular. In my North Yorkshire village they are a common sight and nest in the chimney pots on my street, in fact I'm certain on my chimney stack, certainly last year at least!! This was a reaaly interesting video and a massive thumbs up from me.
  • I don't see Jackdaws very often where I live, but I see them on occasion when I travel. They're probably one of my favourite bird species, I especially love their calls :)
  • @erwinj9697
    They're beautiful, smart and funny to look at in terms of their behaviour. Their eyes are the thing standing out most to me and that has a reason I have seen. They are really focused on where animals and humans alike are looking at with their eyes instead of what they are facing. There have been tests that show if you face a jackdaw but look away with your eyes they know you can't see them and when you are facing the other way but look at them with your eyes they know you can see them. Probably the reason they have such wonderfully noticable eyes because they must communicate with them alot aswell.
  • @mondoprime
    Lovely videos. Currently binging them! Big shout out to same-sex jackdaws!
  • @DoktorPaj
    I fed a few jackdaws some bread this morning. They're beginning to recognize me, and know what to expect when I come around.
