I am delighted to report that this morning is the second consecutive day that I have seen Blue Tits showing interest at our Terrace Nestbox entrances. It is looking like we could be lucky with this location again. It was a small bird I spotted this morning shortly before I topped up the bird feeders – which returned to its business (pecking at the hole) when I came inside. I wonder if more than Blue Tit could use this box this year.
Yesterday lunchtime, shown above, is when I saw the first Blue Tit showing interest in our new, replacement, Nestbox terrace. This box is designed for House Sparrows who are happy to nest in communities – each box being self contained. The Blue Tit shown above is larger than the one that enquired this morning and it was seen chasing off competition yesterday – perhaps unsuccessfully!
Behavioural patterns, shown above, jumping from one entrance to the other was exactly how the Blue Tit behaved last year. I believe the same bird worked on all three nests. I can recall many years ago seeing a documentary on television showing the ability of birds to learn how to get food that was not easy to get at - tests were set up. From memory I believe this programme also reported that birds couldn’t count – they understood one and more than one but if two people went out into a shed and one left they would believe the shed was empty. The Blue Tit may simply not be able to remember which entrance hole he has been through - or perhaps it is wishful thinking on his part and he expects to mate with three females!
The Centre box looks like it could be the favourite of the terrace again. Perhaps the unsuccessful bird might consider a newer detached residence with natural lighting and recording facilities - but I’ll be honest I was hoping for a Great Tit to use this one.
The video, shown above, was taken in my garden on March 2nd 2007.
