Birds of Alcudia, Majorca. 
229. Podiceps griseigena. Red-necked Grebe. 
I observed this species in small numbers on the lagoons 
near Puerto Alcudia in November 1921. 
Included by v. Jordans on Barcelo’s authority. 
230. Podiceps auritus. Eared Grebe. 
Included in v. Jordans' list. 
231. Podiceps nigrieollis. Black-necked Grebe. 
This species frequents the lagoons in the neighbourhood 
of Puerto Alcudia during the winter in small numbers, and 
though they do not remain to breed on these pieces of water, 
they probably remove to the Albufera adjoining for that 
purpose. 
232. Podiceps ruficollis. Little Grebe. 
Not uncommon in suitable localities; there were numbers 
in the Albufera all the year which strayed on to the 
adjacent lagoons during the winter. 
The Grebes, when attacked by Marsh-Harriers, dive 
hurriedly, splashing the water high into the air, possibly 
with the idea of driving off their pursuer. 
233. Rallus aquaticus. Water-Rail. 
Fairly plentiful in suitable localities all the year. 
Obtained by v. Jordans. 
234. Porzana porzana. Spotted Crake. 
Nearly as plentiful as the last-named, and a good many 
are shot in the autumn. 
Included in v. Jordans' list on Barcelo’s and Homeyer's 
authority. 
235. Porzana pusilla. Baillon's Crake. 
236. Porzana parva. Little Crake. 
Von Jordans includes both these species in his list. 
237. Crex crex. Corn-Crake. 
Included by v. Jordans on Barcelo’s authority.
