From the BBC:
Blue tit boom ‘may cause crisis’
Many blue tits will be looking for a … home this spring.
A … boom among … blue tits could cause [a] housing crisis in 2005, according to … experts.Data collected … showed 2004 was a productive year for blue tits, many of whom will now be looking for their first homes.
But natural … sites, such as … buildings, vanish as … houses are repaired.
According to … data, blue tits have an average of just over seven chicks per nest….
It is thought that the average blue tit … will eat about 10,000 invertebrates.
The BTO says that encouraging blue tits … in the garden could provide an ecologically friendly form of pest control.
No word if booby populations are experiencing a similar boom.
I think I speak for everyone when I say, “Nice tits!”
