Thank you Garth for sending this interesting information
Here in west Worcestershire the swallows have had a good season in my parish, and the adjoining ones.
I managed to ring broods in 55 nests, some of which were double brooded, giving a total of 238 juveniles.
I also had a good return of ringed birds from last year, 10 out of this years catch of 43 and was my best average for returning adults.
The average brood was 4.2 and I kept records for the BTO on 35 pairs.
We have just returned from a HF holiday near Malham where there seemed to be no shortage of swallows and one had used a nest I found in a passagway.
A very interesting find was at Bolton Castle, where on Wed 8th Sept I noticed a nest in a stairway still with young, and enjoyed watching the adults coping with all the visitors using the stairs. If there were people under the nest they just sat on a light lower down and waited for them to move away.
As the daylight shortens their inbuilt desire to move south will take over, with them taking two months to fly to South Africa, then stay two months before they return to give us more pleasure next spring.
I didn’t realise that swallows take two months to fly to South Africa. What inbuilt knowledge they have.
Thanks for sending this. It must be wonderful to ring swallows. Is it difficult?
