Rock-Pipit's eggs. The birds at the nest are wary and 

 vociferous. 



34. Lanius collukio_, Linn. 



A male Red-backed Slirike was seen at Gedre, in tlie 

 Gave de Gavarnie, on June 4th, 3265 feet. 



35. Lanius pomeranus, Sparrm. 



On May 31st a male Woodchat in fine plumage dropped 

 out of a thorn-bush upon some insect in the road below 

 St. Sauvenr and retreated with a beetle into thick covert ; 

 2300 feet. On June 7tli we saw a second in a spinney of 

 box below Bucharo, on the Spanish side ; say 4200 feet. 



36. MUSCICAPA GRISOLA, Limi. 



The only Spotted Flycatchers I recognized were at Bagn- 

 eres-de-Bigorre on June 24th among the trees of the river- 

 side boulevard, 1800 feet above sea-level. 



37. HiRUNDO RUSTicA, Linn. 



The only Swallows we saw were at Arrens, in the Vallee 

 d'Azun, on May 28th_, about 2800 feet above sea-level. 



38. Chelidon urbica (Linn.). 



On May 28th a little cloud of House-Martins were enjoy- 

 ing the sunrise among the cliffs at the upper end of Vallee 

 Valentin, above Eaux-Bonnes (3600 feet). Next day we 

 saw more at Ai'gel^s-Vieuzac, and met with the species again 

 in company with the Crag-Martin at the extreme end of 

 Yalle de Ara, under the Pic Perdu, about 7000 feet. To 

 what height will the species go ? I remember coming upon 

 a row of nests under an overhanging cornice whilst climbing 

 (unsuccessfully) for an Eagle's nest, far above the forest- 

 line, in the Dovrefjeld. Between St. Sauvenr and Gedre, in 

 the precipitous glen leading to Gavarnie, a numerous colony 

 of House-Martins breed, especially using the spaces between 

 stone corbels supporting string-courses on the new bridges. 



39. COTILE RUPESTRIS (ScOp.). 



I saw Crag-Martins playing around the Pic de Bergons,6700 

 feet, on June 1st, and observed them later at Gavarnie. We
