Feathered housemates

So, after a year of waiting, the moment is finally there: we have a little birds' nest in our nest box! The fact that I still get manically excited about these things shows how much of a biologist I still am (Dutchies: you may want to watch the documentary 'MeesTV' that was broadcast a short while ago to understand this). I have spent a summer ploughing through forests and fields to check up on literally hundreds of nest boxes and their inhabitants, so you would think I'd be done with them by now, but nope, it's still great.
We'd put the nest box up on our eastern wall, which is the one facing the garden, as high up as possible. This had two reasons: safer from the cats, but also longer sun time. We put it up quite early last spring, in the hope of catching some late breeders, but nothing happened, apart from some stray twigs being put into the box.

Then this spring, some great tits took an interest in the box (incidentally, a friend of mine who is now teaching proficiency classes in English put a question about a 'great tit' on her examination, which led to the test supervisor having to grab the microphone and inform the sniggering first years (and anybody else in the exam hall at the time) that "a 'great tit' is a kind of bird". Seriously, who doesn't know that?). We held our breath, but the birds disappeared again. The house sparrows have been in a frenzy of breeding for a couple of weeks now, so I'd lost all hope, but then last week I came into the garden from the bike shed, and two great tits left the nest box. Very exciting! But also a bit disturbing: if they were leaving when I entered the garden, how would they ever start to breed in there?
Then it started to rain, and it kept on raining for at least a week. So I was sure nothing was happening, as they couldn't have possibly already started a nest, and now they wouldn't be starting one because of the rain. But then today I came into the garden and heard the unmistakable sound of little birds begging for food. So I stood still for a good minute, and as expected: one of the parent birds went into the nest box carrying food, and came out with a little white parcel of poo. Which makes our box officially inhabited! Woo!

The box has a little window up the side through which you can look inside, but as it is about 4 meters of the ground I think I'm going to pass on that one. I think there must be 4 or 5 chicks in there at the moment, reckoning from the sound, but more may still hatch.
The only downside is that the box is quite close to our (always open) bedroom window, so we may get some sleep disturbance from the begging noises. But I'm guessing they've been out of their eggs for a couple of days now, and just aren't as loud as we thought they would be. And otherwise, they'll be gone in two weeks, so I will enjoy their presence for as long as it lasts!
