Nu skal man altid være forsigtig med at bedømme en fugl ud fra blot ét foto.
Imidlertid virker fuglen ikke voldsomt meget større end Almindelig Ryle, hvis man skal bedømme ud fra skarpheden på billedet. Næbbet virker ikke påfaldende langt og slankt, nærmere som et forlænget Stor Præstekravenæb. Benene er ved at blive foldet ind under fuglen, og vil på den flyvende fugl nok ikke stikke tydeligt ud bag halen. Tre karakterer, der kombineret kunn pege i retning af Mongolsk Præstekrave. Det skal dertil siges, at jeg så billedet på jobbet, og derfor ikke har de "finere detaljer" ang. haletegning i mindet. Men førsteindskydelser har før ledt én på vej.

Gerald Driessens fra Belgien har sendt Netfugl følgende kommentar til fuglen:

Hi all,

To me, the Sandplover is beyond any doubt a Lesser Sand Plover Charadrius mongolus.

The typical structure, posture and size are visible. It is very close to Ringed Plover in size. It looks larger because of its greater body-mass and longer legs, but the actual size is actually very similar to hiaticula.

Also, the rounded head, short bill and (especially) the chunky body with broad, slightly upheld shoulders and tapering hind body add to the typical jizz.

I think that the pattern of wings and tail are very variable and of little importance, if not, useless.

You can look at a photo of the Belgian/French bird (1999) at the follwing URL:

When perched, its structure was identical to the Danish bird.

I agree with comments made about jiz and, for me, bill length, all of which point to Lesser Sandplover. The smaller size, more rounde head and, especially, the shorter bill were very noticeable when ringing this species along with Greater Sandplover in Australia on a number of the AWSG expeditions in the 90`s

Netfugl received the following comment from Justin Jansen regarding the ID of the Sand Plover:

Hi Morten,

The Danish bird looks good for Lesser Sand Plover, although the amount on red is low, mostly you suspect this amount of red by Greater Sandplover (race leschenaultii). Based on the amount on red it looks like a western representative of the Lesser Sand Plover group most likely pamirensis.

The flight pictures look good for Lesser SP as there is less black on the edges of the primaries and secondaries. The forehead of the bird looks black and lacks the amount of white that lechenaultii Greater SP should have for example visible on this distance. The bird looks slender instead of the bulky appearance normal for Greater, bill is short good for Lesser Sand plover of the western races, head is rounded etc. In flight the feet seem not to be completely stretched, but when stretched should get over the tip of the tail, and a good mark for the ID of Lesser SP.
Congratulations,

Netfugl received the following comment from Roy Hargreaves regarding the ID of the Sand Plover:

Dear Morten,

I was first struck by the birds size and shape and thought immediately that it was a Lesser Sand Plover. Having consulted British Birds volume 93 Number 4 (April 2000) to make sure I remembered correctly, I believe that it is a Lesser Sand Plover for the following reasons:

1. The legs appear dark.
2. They do not appear to project significantly beyond the tail in flight.
3. The wing-stripe on the primaries appears to be of uniform width and doesn't appear to bulge as in Greater.
4. The bill appears to be short and blunt, particularly when compared to the Greater Ringed Plover on the same shots.
5. No obvious dark sub-terminal tail-bar.

Regards

Roy

Netfugl has received the following comment from Harry Hussey regarding the ID of the Sand Plover:

Hello Morten,

While I have no experience of sandplovers,I feel that this bird is most likely a Lesser Sandplover for a number of reasons. The bill looks 'stubby', with the 'nail' being noticeably shorter than the rest of the bill. While some races of Greater have much shorter bills than one would expect (in particular
columbinus),these still have a longer 'nail' in relation to the total bill length. Greaters tend to look more attenuated at the rear than this bird, and (as others have stated) the legs don't project much beyond the tail in flight, which is another pro-Lesser feature.

Finally,the leg colour,though perhaps being a pointer towards Lesser, has been discredited as a safe ID feature?

Netfugl has received the following comment from Sean Cole regarding the ID of the Sand Plover:

Hello Morten,

It is VERY difficult form your photos, but to me the bird looks like either a Lesser Sand plover or Mongolian Plover based on size, "Jizz" and bill-shape. Due to the amount of rufous on the breast-sides, lacking on the flanks, I would say it is a Lesser Sand Plover (atrifrons). The tail and rump should give it away, but due to the light and distance of the photo, it seems ambiguous.

Hope this helps,

Sean Cole, England

Netfugl has received the following comment from Lee G R Evans regarding the ID of the Sand Plover:

In the light of recent Sand Plover occurrences in Britain, one has to be fairly careful when assigning a vagrant Sand Plover to species.

After carefully studying the selection of images on the Danish Netfugl.dk Rare Birds Gallery, my personal impression is that the images depict a LESSER SAND PLOVER. Most importantly the forehead of the bird appears extensively black and lacks the amount of white that say leschenaulti GSP would show. Furthermore the intensity of the red on the underparts is classic LSP, whilst the bird itself is tapered and elongated.

The bill appears to be relatively short and blunt and overall the body mass of the bird is more akin to Ringed Plover - lacking the heavy structure of GSP. It is very long-legged, upright in stance and particularly round-headed, this posture being identical to numerous recent LSP in the Western P. The legs also appear quite dark and quite unlike the paler lime-green colouration of GSP. In flight, the feet do not appear to project significantly beyond the tail (as they do in GSP) and the wing-bar across the primaries appears to be of uniform width and not bulging as in GSP. Although not directly important and variable within individuals, the bird lacks an obvious dark sub-terminal band on the uppertail.

I have just returned from Turkey where I was able to study a flock of 25 GREATER SAND PLOVERS at very close range. They differed from this Danish bird in body bulk, leg length, intensity of underparts, bill length, stance and structure. I would have no hesitation therefore in proclaiming this bird as a summer-plumaged male LESSER SAND PLOVER. I suspect that as in recent summers the bird will migrate south and be located in Britain in July.

All the very best
