ably increased by migrants in April.

98. Cuculus canorus. Cuckoo. 
A summer visitor, not very plentiful, arriving in March 
or in backward seasons in April. On warm spring nights 
Cuckoos may be heard calling from the hills behind Puerto 
Alcudia, Nightingales singing and Stone-Curlews clamouring 
from across the bay, while Bitterns “ boom ” continually in 
the Albufera. 
Obtained by v. Jordans. 
99. Micropus apus. Swift. 
Swifts arrive early in April, and career in hundreds over 
Palma and less numerously over the smaller towns. The 
earliest date I have noticed them was while crossing from 
Minorca to Majorca on 29 March, 1920, and several were 
over the Albufera on 1 April of that year. 
Included in v. Jordans’ list.
