First and early breeding records for mammals in the UK and Eire


This on-going project attempts to list the first instance of successful breeding for mammal species in captivity in the British Isles. Alan Ashby and Rob Vaughan would be pleased to hear from anyone who can help to fill in gaps or know of an earlier date than the one recorded here. 

There are several species which now breed on a regular basis but for which we do not have a date and location for the first instance. Examples include Red-fronted Lemur, Western Grey Bamboo Lemur, Black-tailed Marmoset, Cherry-crowned Mangabey, Pallas' Cat, Amur Leopard Cat, Onager. It is also hoped to include more subspecies as the list progresses.

All information will be gratefully received but it is essential that the source can be validated, preferably in a published format. If you can help, please use the contact us page or send an email to
