_Blackstart._--Plentiful, though less so than on San Cristobal in Sierra de Jerez (5000 feet). A nest in the crag over-hanging our bathing-place in the burn at San Gerónimo contained five eggs on April 28. We found others on Monachil, and _grey wagtails_ were also breeding at both places. _Bonelli's Warbler._--Arrived, and preparing to nest, end of April: a few _white-throats_ and _rufous warblers_ early in May. Robins and wrens nesting, and _nightingales_ abundant in lower river-valley. _Eared_ and _Black-throated Wheatear_.--Ubiquitous but not abundant. In both these forms (as well as in the Common Wheatear) the males displayed a dual stage of plumage; some being completely adult, while others retained an immature state somewhat resembling their first dress (May). _Stonechat._--Four eggs, April 29. _Blackchat_ and _Crag-martin_.--Both conspicuous by their absence. [This applies to the higher sierra--both were observed in the lower Monachil--say 4000 feet.] _Ortolans_ (apparently just arriving during early days of May), with _cirl_ and _rock-buntings_, were frequent up to the limits of scrub-growth, say 7500 feet. _Rock-sparrow._--Breeding in crags on lower slopes. _Woodlark._--Lower hills: young on wing, end April. _Short-toed Lark._--Lower hills: about to nest here. _Crested Lark._--Lower hills: common. _Tawny Pipit._--Plentiful, scattered in pairs over the arid hills: males singing tree-pipit fashion, soaring downwards with tail spread overhead. _Great_, _Blue_, and _Cole-tits_.--Common, the latter only among the open woods of pine (_Pinus pinaster_). _Raven_ and _Chough_.--A few. _Hoopoe_, _Kestrel_, and _Little Owl_.--A few. _Partridge_ (redleg).--Scarce: a pair and a single bird observed at 8000 feet among snow-patches and junipers. _Chaffinches_ and _Serins_.--First broods on wing, end April; nests for second broods building early in May. _Linnets._--Common up to scrub-limit. _Dippers._--Observed on Genil, Darro, Monachil, and all the rivers visited. _Pied Flycatcher._--A male observed on migration, April 30. In the stupendous rock-gorges which enclose the lower course and outlet of Monachil (3500-5000 feet) are situate the breeding-places of the few griffon-vultures which inhabit this sierra. With them nest some Neophrons, and there is a "Choughery" at 4000 feet, while crag-martins and blackchats (not observed elsewhere), with many blue thrushes, find a congenial home among these giant crags.
