Comings and goings at Napton

Napton, with its small reservoir and locally significant hill, has proven itself over many years to be the most productive part of my patch for migrating birds.

The reservoir in particular acts as a magnet for new arrivals, as well as those gathering to leave or  simply passing through on their way to somewhere else. 

My two April visits, while contrasting in conditions, both lived up to this billing.

A low single figure temperature and biting NE wind made my first trip, on 2 April, a demanding one. Fortunately, it was immediately apparent that some early summer visitors hadn't been deterred. 

A flock of 50+ hirundines swooped low over and around the water, mainly Swallows with a handful of Sand Martins and at least one House Martin.

Three Chiffchaffs sang out around the reservoir, these having been back in the area for a good couple of weeks (this year's first being on 14 March at Leam Valley reserve).  

Perhaps best of all, in a patch not noted for its wading birds, was a Common Sandpiper (or possibly two), bobbing and darting from bank to bank as it made its way around the margins.

A fortnight later (14 April) and it was all change. The weather was transformed to warmth and calm, and the hirundines no longer swarmed across the water (having no doubt dispersed in pairs to their local breeding territories). 

In their place, at least two Willow Warblers had arrived. This was a welcome surprise, since I don't hear the beautiful call of this bird anywhere near enough on my patch, it's numbers having declined markedly in the 20 or so years I've been here.

Another bird which should be much more common than it is is the Yellow Wagtail. Decades ago this would have been a reasonably reliable summer sighting across Warwickshire's farmland, but the few that we have left now are best spotted during spring and autumn migration in hotspots like Napton and (especially) nearby Draycote reservoirs. A single bird running along the bank here was enough to remind me why these sparkling little yellow and green gems are such a favourite of mine. 

The final sign of the twice-yearly wonder that is bird migration came not in the form of a new arrival but as preparations for a mass departure. As if from nowhere 100+ Common Gulls descended on the reservoir, wheeling over the water in a tight ball for 10 minutes before heading off. These are birds which have overwintered inland (perhaps on this very site) and are now on their way back to the coast for summer breeding - almost certainly the last of the patch's winter visitors to begin this return trip.

Aside from the comings and goings of migration there have been plenty more sights and sounds to enjoy at Napton in early April: a Red Kite soaring eastwards to avoid the attentions of mobbing Jackdaws; three pairs of elegantly courting Great Crested Grebes; a small flock of Meadow Pipits; pairs of Grey Heron and Cormorant; and handsome male Reed Buntings in and around the reservoir's substantial reed bed.

Not Waderless!

Reports came in during Friday of a wader-fall at Brandon - six Black-tailed Godwits and a Curlew were among the key arrivals that caught my attention.

Sadly, by the time I could complete my work and get to Brandon, both species had flown. 

With the reserve feeling increasingly quiet, and the weather increasingly ominous, I was left with more usual fare: several Ringed Plovers, 200+ Lapwing, three Green Sandpipers, a Common Sandpiper and a couple of Little Egrets. 

Then came the inevitable heavy downpour which sent me on my way a trifle disappointed at yet another wader dip (see also Waderless, last week).

However, with return migration now well underway it was only a matter a time until something new turned up, and so it proved with Monday's reports of a Wood Sandpiper at Draycote Reservoir.

So, ignoring the rain and the fact that every other birder in the country was in Suffolk, I headed straight to the overflow where it was still being reported through the afternoon. 

It was easily found, busily feeding along the broad stretch of shore from the overflow back along the exposed Hensborough Bank. 

The snapshot doesn't do it justice, in particularly its spangly back which seemed almost black-and-white in the gathering gloom of a rainy summer's evening. That long, strong eye-stripe is a key diagnostic, along with the square white rump revealed in a quick burst of flight.

With the lowish water levels exposing so much of Hensborough Bank it looked perfect for waders, so it wasn't a huge surprise when a Dunlin (already in its winter drabness) flew in to join the juv. Little Ringed Plovers, followed by a Common Sandpiper. 

Two Little Egrets and a number of young Yellow Wagtails kept me company on a contented, if wet, walk back to the car.

Bird of the day: Wood Sandpiper (Tringa glareola), a welcome local highlight which crops up on passage every few years. Only a very few breed in the Highlands, the rest in Northern Europe. They are now on their way to Africa, this one taking an extremely westerly route.
