DNA species ID

chXout® is the UK’s trusted service for DNA bird sexing. We also offer parentage and species ID tests.

A bird DNA test? Not something you hear every day?! Thanks to our rural location we were fortuitously led to developing our first non-human testing service. We were asked to look into the possibility of DNA sexing peregrine falcons and from there hatched chXout®.

Our skilled staff and state of the art laboratories are at the forefront of using DNA technology in ornithology. We provide our bird DNA test services to animals collections, breeders, falconers and the general public all over the UK.

Each year from around April to the end of June we experience a very busy “bird season!” This is thanks to our well-known and extremely popular bird sexing service. Alongside bird sexing, we carry out species identification and parentage testing. All bird DNA test services are available year round for your convenience.


We are able to determine the sex of many species of birds. Our bird species list can be found here. Please remember that this list is continually being updated, so if you are unable to find your species, please do not hesitate to get in touch.

If we have not sexed a bird of your species before, we recommend, if possible, sending a sample from the same species which you know to be female. We can test this alongside your sample to aid our analysis.
