Change in status of the bridled guillemot after ten years*
SUMMARY. A re‐survey of the distribution of the bridled form of the common guillemot, Uria aalge , during 1948‐50 has shown that in the ten years since the first survey was made, four colonies have decreased significantly in percentage of bridled birds and one has increased. The total number of colo...
