caution in the estimation of survival rates
When ashore, a Guillemot Uria aalge usually walks with the tarsus in contact with the ground and this results in severe wear of rings. Even the change from soft to hard metal rings in the early 1960s only increased the useful life of a ring placed on a Guillemot to around 10 years, after which the r...
