The Winds of Change are Afoot - April Bird Report

Whether or not we, as individuals, choose to accept that global warming and climate change are a real consequence of human activities there are certainly variations to be noted that are apparent within our bird populations and their seasonality, at both a national and local level.  Here at the Wig, and its surrounds, wintering wildfowl are leaving us earlier for their breeding grounds and the once predictable arrival and passage of some of our most common migrant small birds appears now disrupted and in a state of flux. Fortunately, there are still many birds for us to enjoy whatever the season; and this April has not been without its moments; so without further adieu a brief summary here follows.

Pale-bellied Brent Geese, from the Canadian high arctic, peaked at 201 birds on the 9th and quickly declined thereafter, with a flock of 23 (including three juveniles) grazing the ‘Twite Fields’ on the 21st. At the same location on the 30th a sleety-snow shower grounded a ‘Grey Brant’ – a possible hybrid between a Pale-bellied Brent and a ‘Black Brant’, or even a species in its own right, depending on which authority you choose to believe; either way a new bird for the blog. There were 1300 Pink-footed Geese at the Scar on the 2nd but come the 25th of the month only eight were to be seen, grazing the abuttal fields at Loch Connell.  After a surprising, but delightful, 62 Whooper Swans on calm water at the Wig on the 1st another 34 of them graced the same location on the 12th.

The usual selection of waders for the time of year was recorded. Dunlins were relatively scarce, peaking at 28 on the 26thRinged Plovers were more frequent, with a high of 108 on the 28th, whilst Knot and Bar-tailed Godwit could only muster 12 and 10, respectively. Whimbrel fared even worse, with a maximum of four on the 28th; there were just two Black-tailed Godwits, mid-month, and a single Sanderling on the 28th and 30th. The 10th of the month saw two Common Sandpipers at Loch Connell.

The maximum number of Teal at Loch Connell was 38 on the 25th. Amongst them loafed a handsome drake Shoveler and close by – constituting their last record of the month – two female Goldeneyes continually dived.  Common Scoters were more numerous on Loch Ryan, with a maximum of just 29. Though numbers of Red-breasted Mergansers were generally low, 102 on the 20th was most welcome. It should be remembered that the weather – be it rain, mist, snow, or the effects of heat haze – greatly determines visibility and the use to which optics, such as spotting scopes, can ordinarily be employed to improve a birders tick list! Many counts, therefore, are rarely definitive but do prove useful as a guide to what’s about. 

Spotting scopes particularly come into their own on mid to long range subjects (weather permitting, of course!). Divers and grebes invariably fall into this category. A flock of six Slavonian Grebes in resplendent breeding plumage were truly handsome, seen at both the beginning and mid-month (in all probability different birds). Their magnificence, however, was surpassed by the appearance of Great Northern Divers, immaculate in full summer dress, with up to three birds on the 13th and 20th. Remarkably, though not quite so well attired, were three Black-throated Divers on the 29th. Not to be outdone, Red-throated Divers – some in breeding plumage, some still in winter apparel – were more frequent visitors on Loch Ryan with 24 birds present on the 29th.

Spring is a time one often associates with migrants. Sand Martins have been with us for some time now but our first Swallow of the season only arrived on the 13th, to be greeted by 10 singing Skylarks in the grassland beside the Wig track.  Wagtails and Wheatears typically favour these same fields on their spring passage but this year, as was indeed similar last year, their absence has been sorely felt. Just four White Wagtails were counted on the 20th and a lone individual on the 29thWheatears fared no better, with one on the 4th, 10th, 20th and 28thAdmittedly, the bird on the 20th was of the larger, more brightly coloured, ‘Greenland’ race; and dandy he was, too. 

Wheatears are the masters of posing, be it on rocks or fence posts 

Gannets were observed in respectable numbers throughout the month with a maximum of 51 on the 30th. Their sheer size, not to mention their striking white and black plumage, helps make them conspicuous. On the opposite side of the coin, the smallness of auks – Guillemot, Razorbill and Tystie (aka Black Guillemot) – makes them relatively inconspicuous at any distance except when occurring in large flocks; needless to say they were only seen in ones and twos.

Sandwich Terns were regular throughout the month: 55 of their elegant forms brought additional charm to the Scar on the evening of the 15th. A single Common Tern (the only record of the month), also on the 15th and two Arctic Terns on the 21st made for a poor showing. An immature Glaucous Gull at the Scar on the 9th was an unforeseen visitor and an actual count of 385 Herring Gulls, also at the Scar, on the 30th made for a refreshing change from the usual guesstimate numbers for this species. Common Gulls, as is typical at this time of year, have almost vacated the Wig and Black-headed Gulls have considerably reduced in number there.

Small ‘bachelor’ parties of Carrion Crows were ever present, along with ‘paired’ birds; two such pairs include birds of hybrid ‘Hoody’ origin. A Raven, though regularly seen, made a splendid sight on one occasion congregating with its smaller cousins which had gathered to forage in the ‘Flash Fields’; a great side-by-side comparison of the two species, and in a field in which I have never  seen a Raven stood before in my 12 years of residence here.

Perhaps the star bird - if one should label it so presumptuously – was a Hoopoe, briefly glimpsed as it fed in a field on the outskirts of Kirkcolm on the 25th; a spectacular one day wonder!

The estate woods have at last come alive with the sounds of summer migrants. Initially there were three Chiffchaffs voicing their ‘slip-slap’ songs on the 1st, nine the next day and by the 12th there were at least 11. Blackcaps were the next to arrive on our patch with two singing on the 2nd, five on the 12th, and eight on the 29thWillow Warblers did not arrive until the 15th when four were heard singing, then nine on the 29th. In previous years ‘Willows’ have outnumbered ‘Chiffs’ but changes in recent woodland management practices have altered the habitat resulting in a shift in favour of the ‘Willows’.

Common Whitethroats are often late to arrive at the Wig and were duly not recorded until the 27thSedge Warblers usually arrive earlier than the preceding species but were not picked up ‘till two days later on the 29th when two birds were vociferous in their proclamation of territory at the marsh.

Finally, let us not forget the humble garden habitat.  Yet again a Tree Sparrow has made a visit to our abode – or to the feeders, I should say. There was one bird on the 24th and, presumably, the very same bird likewise on the 27th. No doubt it did the rounds of all the gardens in the neighbourhood and, perhaps, favoured better stocked feeders than ours! More exceptionally – for us a least – was a Greenfinch singing his little heart out from the canopy of our birch tree, at the end of the month.

With spring passage still ongoing May is likely to be equally rewarding so stay tuned in for the next post.

News from Norwich - An Author Update

Its been a while, but I (Benjamin) am finally back to write another blog post! Back in September I passed this blog onto Eleanor and she has been generating fantastic articles ever since. She is currently doing voluntary work as an Assistant Warden on Lundy and is having the time of her life (seeing all sorts of rare and exciting birds - expect a detailed blog post upon her return!). Our birds certainly haven't stopped though, with plenty of records and new species being seen around the Wig. Expect an article soon! In the meantime I thought I would give you a little update on what I've been doing, as well as a taster of the bird watching scene down here in Norfolk.

I've had an exciting past few months working on my PhD, studying the effects of microplastics on salt marshes. Not only does this have exciting chemical and environmental implications, visits to salt marshes present a great opportunity for bird watching! My first visit exemplified this, adding not only new species to my growing Norfolk list, but a brand new species for me -  the Great Egret! Another species you don't see round the Wig are Avocets. Alongside these beautiful waders we also get some more familiar species, such a Brent Geese (a nice mix of Pale and Dark Bellies), gulls of all varieties and more common waders like Redshank, Turnstone and Curlew. The marshes are also havens for raptors, including Buzzard, Kestrel, Peregrine, Red Kite and the aptly named Marsh Harrier. There has even been a White-tailed Eagle in the vicinity, however I have not been fortunate enough to see it yet. 

The UEA campus has a fantastic walk around its lake

Field trips aren't the only opportunity for a spot of ornithology, as the University of East Anglia has a wonderful campus. Situated on the edge of the River Yare, it features woodland areas, open fields, marshes, reed beds and its own lake! My lunch time campus walks often end up lasting longer than intended as I explore the nooks and crannies, or see another new species for my campus list. Some of my favourite spots are the riverside walk, which is good for Blackcap, Greenfinches, and in the winter Siskin. No river would complete without Kingfishers though, and there is a pair which traverse this stretch quite regularly. I also really enjoy the small marsh just past the student accommodation. Not only is this great for ducks (Teal, Shoveller and Gadwall!), but its the first place I have ever seen Swallows, House and Sand Martins, and Swifts all sharing the same skies. It also has Common Tern, Grey Wagtail, Stonechat and Snipe, so despite the frequent chilly winds it is definitely the most lucrative spot around the University. Perhaps my most surprising campus record was a Harris Hawk! I was rather shocked to see one perched in a tree by the main buildings. Having seen it several times since I now know its a tame pigeon hunter, but still a stunning bird to look at. 

Bowthorpe Marsh is just a short walk of the campus

During my first couple of weeks here I quickly noticed the differences in bird variety when compared to Scotland. A lot of the species I used to take for granted are very uncommon in Norwich, including Rooks, Chaffinches and House Sparrows. I often have to go further a field to get a glimpse of these species. In return though, many birds are more common down here, including Green Woodpecker, Magpie and Long-tailed Tits (these are a daily species for me - a very pleasant surprise!). And then there are the species which we do not get around the Wig at all. Egyptian Geese are very common all around Norwich, with many now having goslings. Cetti's Warblers are quite the opposite, uncommon and illusive they can be quite difficult to pin down. Fortunately I have found a few spots where I can listen out for them, and if I am really lucky, catch a fleeting glimpse before they dive back into cover. Finally, whilst not a bird, Muntjac deer can be found across Norwich - if you can spot them! I have seen them quite a few times on my weekly walk up the rivers edge, but have also seen them on the edge of parks, and once on the hospital gardens! 

The different lowland habitats not only mean different birds to see, they have also made a gradual change to my birding habits. With my local patches being dense woodland or reed beds and marshes, quite often you will hear more birds than you will see. This was a little frustrating at first, as identifying bird calls has always been my biggest weakness. However, regularly visiting the same spots has slowly improved my confidence, and now I can ID many species including Greenfinches, Chiffchaffs and Blackcaps. Whilst the majority of calls I know are of common birds that I also often see, it has been a great moral booster, and I look forward to expending my auditory roster even further. 

A walk along the River Wensum is the staple of my bird watching 

As you can see I've been having a great time, and these are only from my local patches! I still have so much of Norfolk to explore, and so to aid this I have taken on a WeBS site. Yet another marsh (you'd think I would tire of them between my project and bird watching), its quite a large site outside of Norwich. I have only visited it once so far, but even that brief stint yielded the eponymous Marsh Harrier, Reed Buntings, and four species of Geese, including a Lesser-white Fronted Goose! Other species will definitely put my listening to the test with Grasshopper, Reed and Cetti's Warblers all having been recorded there in the past. All in all it seems like a great site, even if I did manage to get lost and fall in a bog whilst there! I look forward to visiting it again over the coming months, as well as venturing off further into the Norfolk countryside to explore. 

That's all I have time for at the moment, but hopefully there will be some more content on the blog to tide you over until Eleanor returns. I will certainly try to write a few more articles, as Eleanor pointed out I have actually only written 48 articles myself so I need to round that up to a nice 50. Until then, happy bird watching all!
