Len Pick Trust Owl Project
Welcome to the Len Pick Trust's owl project. A number of years ago we worked with local technical colleges and local farmers to build two owl towers on land around Bourne. These structures have proven to be very successful, and during the nesting season we run a blog and live video feed from one of the towers, which you can find below.

Several trustees from the Len Pick Trust and their families were present to see the three owlets ringed under licence last night.
They were sexed as two males and one female.
The chicks are exactly seven weeks old and in the evening they are mobile enough to go down the tunnel to the entrance as they know this is where the food is delivered.
They return to sleep in the box during the daytime.
Regular viewers will have noticed our camera has been unreliable this season but it is working now.
The website has already had nearly ten thousand hits in 2026 so far.
It is popular in countries all around the world.
It won’t be long before the owlets are taking their first tentative flights but they will return to the tower during the day.
We must make the most of these views as they will soon be gone.





The weather is improving and our barn owl chicks are looking healthy.
They don’t need brooding now and so the female can help with the hunting.
We can expect to see just the chicks in the nest through the night as the adults will be busy.

The owlets are three weeks old and are doing well despite the recent heavy rain.
Much of this fell during the day so the male has been able to hunt through the night.
The chicks won’t need brooding from next week so the female will begin to share the hunting.

It is two weeks since our oldest chick hatched and the brood of four are thriving thanks to the good weather.
This week a short tailed vole was brought in by the male which is a really good sign as only field mice have been seen in the nest chamber so far.
Voles form most of the diet of barn owls in the UK and they have been scare in the East Midlands so far this year because of the late winter weather.
However, in these optimum conditions, they can soon increase their numbers very rapidly and it appears this will now happen in time for our growing family to benefit.

Exciting news from the owl tower today.
Our barn owls have a brood of four chicks.
They are feeling the heat ((aren’t we all?) but they are coping well.
The male is bringing in lots of field mice.
The female won’t hunt until the chicks are two weeks old.
It is possible all four chicks will fledge in two months time.
The main factor will be the weather. If it gets very windy, with overnight rain, the adults will struggle to hunt and the brood will deplete.
This is quite natural .
The older chicks will then get the most food. That’s why the eggs hatch at two and a half day intervals.
Let’s hope they all make it.

It was very hot in the owl tower today so the female barn owl didn’t need to brood the chicks.
This gave us a rare opportunity to see the three tiny owlets.
There is still plenty of time for the fourth egg to hatch.

This morning we can see a broken eggshell near the female.
It will be a matter of luck when we see the chick itself as she will brood it closely.
If all the eggs hatch we should have a full brood by the middle of next week.

Today we briefly saw the fourth egg.
It was laid last Friday.
The female barn owl will do all the incubating and we can expect the first chick to hatch in the third week of May if all goes well.

Tonight the female barn owl lifted off the nest to reveal three eggs. The third would have been laid on Tuesday evening.
The fourth egg should be here by Friday lunchtime.
The male provides all the food for his mate during incubation. Viewers will notice he disappears for long periods at night. The settled weather this week will help him to hunt.

This morning the female owl laid her first egg.
There has been a build up of prey brought in during the past two or three days by the male.
Barn owls incubate their clutch from the first egg, meaning the chicks hatch at different intervals.
Eggs are laid at approximately two and a half day intervals so we can expect the next egg later on Sunday night.
