l^'he Great Northern Diver is a regular winter visitant to 

 Portugal, and is well known on the lagoon at Aveiro, Mur- 

 toza, &c. I have seen specimens obtained in the months of 

 November, December, and January, and there are some in 

 the Lisbon Museum from the Tagus. On the 30th January, 

 1884, I saw a specimen near the Lazaretto at the head of 

 Vigo Bay.

The Little Grebe is resident, and very abundant on tlie 

 Ovar- Aveiro lagoon, chiefly in winter. The country people 

 tell me that it nests along the sides of the streams and 

 among rushes.
