Some 60 miles east of the Atbara river and below dome-like jebels (granitic inselbergs), are Kassala and c.2,800 km² of the Gash river delta cultivations watered by the ephemeral flood from the nearby Eritrean mountains during July-September. Beyond, to eastward, are the barren-looking Red Sea Hills.
This is the first significant stop-over area in autumn for Palaearctic migrants that have crossed the desert terrain of NE Sudan. Brief visits (September) found several thousand Yellow Wagtail (several forms) feeding in the delta; also European Swift, Sand Martin and European Swallow and Hoopoe; a Hobby (with desert locust swarm), and occasional Short-toed Eagle, Little Egret and European Roller. Across the verdant plains were Montagu’s Harrier, Blue-cheeked Bee-eater, White Stork flocks, numerous Isabelline and Northern Wheatears; with Woodchat and Red-backed Shrikes in bushy places, also Hoopoe. Small rain pools attracted occasional Glossy Ibis, Grey and Purple Herons, Garganey and White-winged Black Tern as well as a few waders: Avocet, Black-winged Stilt, Little Stint, Curlew Sandpiper, Greenshank, Wood and Green Sandpipers, Black-tailed Godwit and Ruff. Gardens with shrubberies and trees in Kassala held Spotted Flycatcher, Lesser Whitethroat, Blackcap, Garden and Olivaceous Warblers, Black-eared Wheatear, Thrush-Nightingale and Common Redstart (eastern race samamisicus). Wintering birds seen were Pallid and Marsh Harriers, Common Kestrel, Masked Shrike and Short-toed Lark.
