Could go for black grouse and ring ouzel. Maybe garganey will have arrived. April Still good for woodpeckers and goshawk. As the month progresses we seek to welcome in each of the Summer visitors. A good chance to learn or relearn to recognise by song.
Marsh harriers arrive now.
The North West has a good passage of little gulls. Late in the month is best for grasshopper warbler, lesser whitethroat, pied flycatcher and wood warbler. We look out for passage of white wagtails early and whimbrel later. Late in the month, if the winds are right, there can be a good passage of pomarine skuas off North Cumbria. Well worth going for if we can time it right.
