Day 214 - Jolly clever Jackdaws

Jackdaw (Corvus monedula)
Hey everyone, it's Friday and day 21? and I hope you are looking forward to a great wild weekend and have lots of great things lined up to support the Wildlife Trusts #30dayswild. Well it took me a while tonight to decide what to cover as I need to get my photos in a better order and I couldn't find the species I wanted to do. What I did find though was two nice photos of a visitor to my garden that is quite camera shy, it doesn't like me moving to get my camera let alone photograph it. I did sneak these shots though of a lovely Jackdaw.

As usual I did some research and here's what I found:
  • They are resident all over the UK apart from North-West Scotland. They are even found on the Shetlands and Orkneys.
They are very observant - saw me taking the photo!
  • There are about 1,400,000 breeding pairs of Jackdaws across the UK. That means there are around 6 pairs of Jackdaws for every square kilometre in the UK.
  • They are found in all habitats around the UK mostly in Villages and Towns. They are least found in Bogs, Reed beds and Moorland.
  • They first breed at 2 years old and live for about 5 years but the oldest wildly exceeded this at 17 years and 22 days.
  • Adults usually weigh about 220g but they can range from 196g to 265g. Juveniles usually weigh around 205g but can range from 151g to 259g.
  • The egg weighs about 5% of the adult's bodyweight at 11.1 grams. The ring size is usually an E.
  • Their length is around 34cm and their wingspan is about 70cm. The egg is usually 35mm by 25mm.
  • They only ever have 1 brood a year of about 4-5 eggs with and incubation time of 20 days and they fledge between 32 and 33 days after hatching.
  • Well now to the Jolly Clever bit. Folklore has it that Jackdaws are very intelligent. They are supposed to steal jewellery and keep it in their nests. Turns out there is no evidence for this but they are intelligent and can be taught to tricks. There are also a lot of stories about them caring for injured relatives.
Here are some links to some more information:
