I'm a wildlife cameraman.
I travel all over the world filming wildlife
but I've spent the past year seeing what
I could photograph around where I live.
[SCREECHING]
Some males seem to be
incredibly persistent.
This chase went on for minutes on end.
Despite their large eyes,
barn owls hunt mainly by sound.
They can pick up the faintest
rustle or squeak of a vole.
[BLACKBIRD ALARM CALL]
They're making a nest
from an amazing recipe
of moss and lichen
stuck together with spiders' webs.
More than anything else
it was cubs I really wanted to film
and I thought this female might have some.
[CROAKING]
They've come too far down the field towards me.
I don't want them quite this close. 
A long spell of bad weather doesn't help.
[THUNDER]
This could all end in disaster.
