A recent communication from the BTO requests nests to
be sent to Cannelle Tassin de Montaigu, a PhD student at Sussex University, who is
currently working on the impact of pesticides on songbirds. Although bird
protection law permits the cleaning out of nests between 1st
September and 31st January, some hole-nesting species, including
sparrows, may have second or third broods in the same nest. Therefore, their
nests should be left until later in the autumn when it is certain that they are
no longer in use. However, once you are certain that the nest is no longer
in use, then please consider sending it to Cannelle, to further her important
research, part of which, as she explains, is “to understand the exposure of
chicks to pesticide within the nest. Birds' nests are composed of a wide range
of materials, often including animal-derived materials such as feathers, hair
and fur. Parasite treatments are applied on pets and livestock on a regular
basis, which could potentially end up in a bird's nest. We intend to find out
if chicks are exposed to these treatments.”
All you have to do is fill in a short form with details of the nest, and send it
and the nest to Cannelle Tassin de Montaigu, PhD student, Evolution,
Behaviour and Environment School of Life Sciences, University of Sussex,
Falmer, Brighton BN1 9QG.
Cannelle can be contacted at ct430@sussex.ac.uk
One of our members, Laura Bimson, has already sent in three nests from her garden in Liverpool 12, photos below. It would be great if more of our members could do the same, and help to further this important research.
Successful blue tit nest in Laura's garden
10 eggs, 8 chicks
Successful starling nest in Laura's garden
4 eggs, 4 chicks
Unsuccessful starling nest in Laura's garden
5 eggs, 5 deceased chicks
FURTHER INFORMATION
From the Nesting Neighbours participants
We hope this will help us understand the exposure of chicks to pesticides within the nest and the impact on songbirds.
Birds’ nests are composed of a wide range of materials, often including animal-derived materials such as feathers, hair and fur. Parasite treatments are applied on pets and livestock on a regular basis with a variety of veterinary treatments and they could potentially end up in a bird’s nest. We intend to find out if this happens
Method
So that we can keep track of which nest came from where, please fill in the form below and include in with your nest(s).
Nest(s) should be place in a closed bag (Ziploc bag, envelopes) with one nest per bag. If you are sending multiple nests, please make sure you label them in some way (number on the bag/envelop).
If there are unhatched eggs or dead chicks please leave them in the nest.
You are advised to wear gloves and ensure the Ziploc bag is closed outside. Wash your hands after handling the nest.
