Looks like a good option for our nest.

These two Great Tits spent sometime investigating the nest boxes in our bushes and one even had a look inside this one. Maybe one might be occupied shortly.


For householders who still get their milk delivered in glass bottles, waking up to find the foil lids have been pecked open may seem little more than a rather annoying piece of avian thievery. Yet these cream-skimming birds are actually the last surviving practitioners of one of the first widely recognised examples of culture in animals, other than humans.
 

And now scientists studying how this behaviour first emerged and spread among populations of great tits during the 20th century have made an even more startling discovery - the birds not only pass on cultural traditions, but will change them to conform to those practiced in the local area.
