46 The Ooiogisls' Record, Ju tie i, 192 1. 



Warbler's) between 6.30 to 8 a.m., and 5 to 6 p.m. The alarm note 

 always appeared to come from a bird, presumably a hen, that wished 

 to go to its nest. Any bird returning to its nest to sit, always tried 

 to drop almost vertically on to it from a tree or bush above — 

 sometimes a drop of 10 feet or so, but in many cases there was no 

 vegetation of any height above the nest and the drop was a very 

 short one of a foot or so. Needless to say a sudden drop from a 

 tree or bush should always mean a certain nest. My dates for eggs 

 were as follows : — i6th May, c/5, c/5 (nearly hatching), c/5 (con- 

 siderably incubated) ; 19th May, c/5, c/5 (incubation sliglit) ; 

 20th May, c/5 (nearly hatching) ; 23rd May, c/4 (incubated two 

 days) ; 25th May, c/5, c/5 (incubated i day), and c/4 (incubated 

 2 days). 



I am nearly certain that the three nests of 28th May, were the 

 second nests of the three lots of i6th May, as each nest of those 

 of the 28th, was within 15 yards of those of the i6th. On 17th 

 May, these presumed second nests were being built in a great hurry. 

 Quick work to build and lay a full clutch of eggs in 11 days, and 

 curious that all three pairs should complete their several tasks in 

 exactly the same time ! 



The eggs of Bonelli's Warbler that I found were much like 

 Wood Warbler's, but on an average decidedly smaller, and the spots 

 have a more ruddy tinge. 



The only other Warblers I have met with breeding in Spain 

 are the Great Reed, Reed, Blackcap and Whitethroat, but as they 

 are well-known in England, except the Great Reed, I do not propose 

 to say anything about them except that the Great Reed, Acro- 

 cephahis anmdinaceus (L.) appears to be only locally common, 

 nests in colonies and has normally five, and sometimes six, eggs 

 about 20th May. 



If any reader of these notes meets with the Sedge Warbler, 

 Acrocephalus schoenohaemis (L.) or Aquatic Warbler, Acrocephalus 

 aquaticus (Gm.) or Garden Warbler, Sylvia borin (Bodd.), breeding in 

 Andalucia he will be doing useful work for ornithological science 

 if he records the same. It has been stated in print that the Aquatic 

 and Garden Warblers do breed there, but neither I nor. anyone I 

 have met, who has worked there in recent years, has ever found 

 either of them in the breeding season.
