Bluetits

Investigating bluetits
still undecided.
Will they use my nest box here?

Is it too late now,
have they nested elsewhere
or is it still too early in the year?

Bluetits apparently have to time their nesting just right, they only have one chance in the year and must have the young hatch when the spring is well enough advanced for the caterpillars and grubs that they eat to be plentiful. This recent cold spell can’t help. Perhaps the next few weeks will make it clear if they will nest in my nest box or not, meanwhile they still keep checking it out!
