Seeking Southerlies

I had some time available for birding this weekend. Walking home from work on Friday this Blackcap in the Hermitage seemed to herald a hot migrant-filled weekend. A quick look at the synoptic charts soon put paid to that hope.

Instead, I decided that, since the weather patterns were set against a deluge of migrants, I would try to mop up some of my many missing Lothian year ticks. I popped into Blindwells on Saturday morning and added House Martin and Grasshopper Warbler. Several dog walkers seemed to be encouraging their pets down to the waters edge unfortunately so any hope of Garganey seemed unlikely. At Ferny Ness I failed to pick up any Red-necked Grebes but a quick stop at Seton had me jamming into two Brent Geese - I have missed this species in the county several times over the last few years so this species definitely felt like a bonus. At the latter site Sandwich Terns were much in evidence - some species at least are able to battle the headwind.

Today I birded a few of the sites further east, but it was hard work in the cold conditions with scant reward. An early start at Spike Island produced 4 Whimbrel. Returning to the car a Brambling lifted my spirits. At Scoughall I studied the gulls following the potato planting but could not pick out anything unusual so had to content myself with a seawatch to add Puffin and Guillemot to the tally. Three smaller terns passing northwards turned out to be Arctic Terns - another species I missed out on seeing in the county lasyt year.

I then headed to Barns Ness for a quick look for the Wryneck seen on Friday. No joy although it was seen later in the afternoon apparently. Up to Johnscleugh for a moorland route home - not exactly a short-cut, but a good plan to notch up Red Grouse, Common Sandpiper and (below) Red-legged Partridge. The Ring Ouzels will have to wait another day as I ran out of time before I could head to Faseny. All in all an enjoyable tour.

Juvenile Glaucous Gulls on Berneray

 
West Beach on Berneray must be one of the most spectacular beaches in Britain - in fact it is so beautiful that it was once used to illustrate a Thai holiday brochure. Of course, the temperature does not reach that of steamy South East Asia and, as if to emphasise the point, a couple of juvenile Glaucous Gulls were parading around close to a stranded seal carcass. On size and head-shape I would suggest the larger bird above is a male and the bird below a female.

These birds were heavily bleached and in a quick flight view of their patchy upperparts I think I might have identified them as 3CY rather than 2CY. Up close their bare parts seem to confirm the younger age class. Though, since these are the first Glaucs I have clapped eyes on in several years I am not claiming any expertise...

Carrion Crow vs Shore Crab: fight, fight, fight!

If you have ever wondered who would win in a fight between a Carrion Crow and a Shore Crab then here is your answer. Unsurprisingly, it is the intelligent, adaptable, avian predator-scavenger that comes out on top.

Photographed at Barns Ness in East Lothian last Sunday morning, this crow carefully manipulated this female crab onto its back and then twisted its tail off. After swallowing the tail the crow continued foraging, leaving the hapless crab to scuttle off, possibly mortally wounded.

I was left wondering whether the crab would survive, whether the crow had been hoping for an egg-mass under the crab's tail, whether the handling costs of dealing with the rest of this meal were just too high for the crow, or whether this behaviour would benefit the crow by eliminating a competitor from its patch.


Reaching for Birds of the Western Palearctic I find that crabs are not even listed as a food source for the Carrion Crow - the only Crustacea mentioned are woodlice and crayfish. Presumably there were no published studies of the diet of shoreline crows, as I am sure crabs would feature regularly. Certainly having been fortunate enough to have been working on BWP at the time Volume VIII was written and I can certainly vouch for the thoroughness of the research.

Balranald Redshank

The drive in to Balranald RSPB on North Uist is a classic location to photograph Redshank and other waders on the rocks and fenceposts. This one was one of the early-birds on territory - most seemed to be content to be poking around the extensive shoreline of the island.

Rock Doves rock

If it wasn't for the ubiquity of the feral pigeon living as a commensal species in human-altered habitats, people would rave about the delicate beauty of the wild Rock Dove. This pair were photographed from the roadside earlier this month at Clachan on North Uist. Unlike the feral pigeon, these Rock Doves were skittish and vanished almost as soon as my car my car came to a halt.

Lesser Black-backed Gull mobbing White-tailed Eagle

An adult Lesser Black-backed Gull is mobbing a (probable 2CY) White-tailed Eagle last week. Life in the Uists must be a constant barrage of mobbing from gulls and shelduck for these massive eagles.

Great Black-backed Gull mobbing White-tailed Eagle

I have posted an aerial shot on this theme previously, taken in Harris in 2011, so I thought I would add a North Uist shot from 2012. Spectacular stuff, even when watched from a distance.

Otter on Berneray

This uncropped shot was taken during one of the most exciting wildlife encounters I have ever had - an otter choosing to come ashore right alongside to eat a fish. Of course, there is always a challenge - in this case heavy rain and dark cloud. After twenty five minutes of close-up otter action I had several hundred images. Only after the otter sank back into the sea did I realise that I was soaked to the skin and frozen!

Merlin

We have just returned from a week on North Uist, Berneray and Benbecula - a truly beautiful part of the world and a fantastic place to watch wildlife. As expected we saw plenty of raptors, including close and prolonged views of this Merlin - a second calendar year bird still in its juvenile plumage.
