A summer visitor, not very plentiful, arriving in March 

 or in backward seasons in A[)ril. On warm s[)ring 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.

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.
