All the Swifts which we collected appeared to have 

 extremely white throats. The Pale Swift is a migrant to 

 the eastern Canary Islands, arriving, according to Polatzek, 

 at the end of February and departing in September. This 

 observer records it only as a bird of passage in Lanzarote 

 but found it breeding in Fuerteventura, where Meade- 

 Waldo also discovered a colony. I found these Swifts to be 

 plentiful in the eastern group during May and June, but 

 ])articularly so in Fuerteventura. Here, in the neighbour- 

 hood of Puerto Cabras, they were seen in numbers hawking 

 over the plains; they were also met with throughout our 

 journey in the island, being especially numerous at Toston, 

 in the valley of La Peiia, and at Antigua. I did not myself 

 find any nests, but Swifts doubtless still breed plentifully in 

 this island. 



In Lanzarote they were much less common, and were only 

 seen in any numbers at Tinosa and once over the town of 

 Haria. Single birds were noticed from time to time at 

 various points on the route. They were not seen in Graciosa, 

 but they were found on both the small islands of Montaiia 

 Clara and Allegranza, in the former of which they appeared 

 to be breeding in the cliffs. 



A series was obtained from Fuerteventura, Lanzarote, 

 Montaiaa Clara, and Allegranza.

This little Swift was seen on several occasioi s in Fuerte- 

 ventura, where it was not nearly so plentiful as the preceding 

 species, being, in fact, quite rare. A few were recognised 

 hawking with M, m. brehmorum, over the plains near Puerto 

 Cabras in Fuerteventura. In Lanzarote they were not seen, 

 but I should be much surprised if they do not nest in the
