April is the month when the trickle of Spring migrants we see in March turns into a torrent. This year I've decided to feature four species and I've chosen them for no other reason other than I particularly enjoy seeing them. They all have striking plumage and, apart from the black and white Ring Ouzel, are particularly colourful; they also have the added spice that they are relatively scarce and we only see them for a short period of time on migration. I have chosen Ring Ouzel, Yellow Wagtail, Common Redstart and Wood Warbler, with the former two in this month's newsletter and the latter two in next month's (also see bottom of this article).
The Ring Ouzels that pass through here in spring will have wintered in southern Spain and the Atlas mountains of north-west Africa although a few may winter further north than this, perhaps even as far north as this country. Although all the birds we see around the Dee Estuary are undoubtedly passage migrants one or two pairs still breed in the eastern hills of Cheshire with more over the border in Derbyshire and further north along the Pennines. Most of these British breeding birds are back on their territories by late March/early April. It is probable that the birds we see in March are these British birds which pass through quickly on their way to the hills. However, as can be seen from the graph, the peak of the passage here does not occur until the third week in April and these will be mostly, if not all, Scandinavian breeding birds. Normally, these birds have all passed through by the end of April with only one May record in six years of an 'odd' bird, perhaps a failed British breeder.
Some of the birds which pass through in April pause here for several days, as they did in 2007 and 2010. In 2007 we had a female in Caldy (just below Stapledon Wood) and a male in Heswall Fields, both of which stayed for five days. In 2010 we had a male and female staying for at least a week in the fields along Lingham Lane, by Leasowe Lighthouse.
The more normal pattern is for birds to stay just a few hours before moving on. Numbers vary greatly from year to year, presumably due to weather patterns during migration, with most Scandinavian birds usually migrating up the east coast. The norm is to see just single birds, but sometimes two or three can be seen together and on April18th 2010 as many as six may have been present on North Wirral.
The best sites to see this species are Hilbre, Royal Liverpool Golf Course (between Red Rocks and West Kirby), the fields just inland of Hoylake and the fields between Meols and Leasowe Lighthouse.
These bright yellow birds wouldn't look out of place in the Amazonian rain forest, and look truly exotic in the horse paddocks of north Wirral! They winter in West Africa, typically Senegal and Gambia, and migrate north through Morocco, Spain and France before reaching the Dee Estuary. Although declining as a breeding bird they still nest in Cheshire and North Wales, and several actually breed just inland of the Dee Estuary in the Shotwick Fields area. The birds we see along the coast at Gronant, Point of Ayr, Hilbre and north Wirral are passage migrants and it is these birds which are included in the graphs below.
Perhaps because they have further to travel the peak of the migration is a week later than for Ring Ouzels, and good numbers can still be around in early May before tailing off to the end of the month.
As you can see from the graphs they are more numerous than Ring Ouzels, and last year was a good one for this species. Even so, records of just two or three at a time is the norm, 12 on April 28th 2010 in horse paddocks by Leasowe Lighthouse was the highest number recorded there in the past six years. In 2010 they were recorded daily from April 21st to the end of the month, but on only four days in May.
The most reliable sites to see this species are Hilbre and the fields around Leasowe Lighthouse, but they can turn up just about anywhere in the the fields and shore surrounding the estuary.
Whilst researching for next month's article I realised that many of both these species start turning up in April - i.e. before the May newsletter is published! So you don't miss out here are the most likely dates to see these birds in April, and the best locations:
Redstart - birds start appearing in early April, but most are seen in the second half of the month. They may be found in the typical migration hotspots, with Hilbre and Leasowe Lighthouse the most favoured.
Wood Warbler - in the past six years the earliest we have seen this species is April 23rd. They rarely stay more than a day or two; birds may then be seen until the end of April and into the first week of May. They don't normally pass through the usual migration hotspots, preferring instead mature woodland. Stapledon Wood, Caldy, is a good spot for them, as are the woodlands on the Welsh side of the estuary such as Wepre Park, Greenfield Valley and Garth Wood.

Once again the RSPB are organising voluntary wardening at Neston Reed Bed, the scheme will begin near the end of March and run through until the end of May. Wardening will take place each evening in order to protect this important habitat from disturbance. I know in the past this scheme has attracted birders who have realised what a good opportunity this location is for some serious birdwatching with the possibility of seeing migrating Ospreys and Marsh Harriers, large numbers of Little Egrets flying in to roost, Bearded Tits, Hen Harriers, Short-eared Owls and the numerous birds which breed in the reed bed. If you are interested please contact Geoff Robinson (Geoffrey.Robinson@rspb.org.uk), telephone 0151 336 7681.
The spring migration started with a White Wagtail on the 11th and Sand Martin on the 12th. That was the earliest Sand Martin since 2003; the first Willow Warblers and House Martins were also earlier than normal. By the end of the month birds were coming in in larger numbers with 40 Sand Martins on the 26th at Inner Marsh Farm and 10 Wheatear along north Wirral on the 30th.

The last day of the month resulted in a westerly gale bringing with it a record number of Little Gulls past Hilbre, 651; also a good count of 228 Gannets on the same day. Other migrants not tabulated included a Whimbrel over Wallasey Golf Club on the 2nd, the first Sandwich Tern off Hilbre on the 14th, 1,700 Meadow Pipits and two Ospreys on the 29th and single Ring Ouzels on the 24th and 29th. Although some Blackcaps and Chiffchaffs over-winter in this country there was an obvious influx of migrants into the area during the month.
The high spring tides of the 20th to 22nd produced more good birding, the sea came well into the wall at Riverbank Road and Heswall Golf Club. Highlight was six Short-eared Owls on the 20th with seven the following day, a good selection of raptors was also seen.
Several days of calm conditions meant that birds were easy to see on the sea off Hilbre and north Wirral and included 47 Scaup on the 6th, 35 Goldeneye on the 7th, a Black-throated Diver and 19 Red-throated diver on the 10th, a Great Northern Diver on the 12th, 162 Great Crested Grebes on the 18th, two Velvet Scoters and 150 Common Scoters on the 20th. A 'probable' American Herring Gull was present on several days, as were two to three Yellow-legged Gulls and a Mediterranean Gull. 192 Brent Geese on Hilbre on the 13th was a very high count for March and a Long-tailed Duck was off Hoylake on the 11th. It is not often we see Wheatears and a Snow Bunting on the same day, the latter turned up on the sea embankment at Leasowe Lighthouse on the 13th when the first Wheatears came through.
As suggested in the above article the spring migration will really hot up this month. We can expect to see our first Tree Pipits, Whinchats, Redstarts, Yellow Wagtails, Grasshopper Warblers, Whitethroats and Swifts. Hopefully we will also get a good 'fall' of birds - sometimes we can go out early morning and every bush seems filled with Willow Warblers, the fields are covered in Wheatears and the beaches full of White Wagtails.
Out to sea Little Gulls will be flying past Point of Ayr, Hilbre and north Wirral on their way to Crosby and Seaforth before flying across the country and on to the Baltic to breed. Gannets will also be heading north in the Irish Sea and sometimes we can get several hundred off shore this month. Whimbrels will be passing through with the best sites for these being Heswall Shore and Hilbre.
Among the many migrants may lurk a rarity or two although it would be too much to hope that a Red-rumped Swallow will turn up for the fourth year in a row. Other April rarities in recent years have included a Red-breasted Flycatcher, Great Grey Shrike, Black Kite and White-tailed Eagle. There would appear to be at least two singing Cetti's Warblers in the Neston Reed Bed area so it would be nice if we could confirm that they are breeding here - they were first proven to have bred in Cheshire in 2009.
There were still a lot of Waxwings in the country in March and we may well get a good size flock dropping in here on their way back to Scandinavia.
