A pretty little Blue Tit. Not our smallest tit species but very common and well known by most people in the UK.  They are actually a feisty little bird and quite bold and brave.  When I trained as a ringer handling a Blue Tit always meant that you would get a few pecks to the back of the hand. Being about 12grams in weight as an adult means that they need to feed very often and consequently they are a very active species.  Males are usually brighter, bolder and a little more brightly coloured.

The Jay is a a bird that I see on every visit to my hide this last couple of weeks. I have a pair visiting together and I recognise them as individuals. I can therefore say that this is the female who has a slightly less aggressive looking head and beak.  Jays are very intelligent and powerfull and can be aggressive to other smaller birds, even feeding on them from time to time  if the mood takes them. However, my observations over the last few months seems to show that the small birds are not aware of this as they rarely "alarm" and leave the scene when the Jays arrive

Great Tits are the largest of UK tit species. Again males are more brightly coloured than females but as well as that, males have a broad black band that shows right down the breast and between the legs. The dark band on females is much less pronounced.
