  Calidrid
The calidrids and their allies are a group of Arctic breeding, strongly migratory wading birds.
Their bills have sensitive tips which enable them to locate buried prey items, which they typically seek with restless running and probing.
There are a number of species closely related to the calidrids which are listed after the main list.

The calidrids and their allies are a group of Arctic breeding, strongly migratory wading birds.
There are a number of species closely related to the calidrids which are detailed at the end of the main list.
The Stilt Sandpiper, Micropalama himantopus, has particular resemblances to the calidrid sandpipers, especially Curlew Sandpiper, and is sometimes given the scientific name Calidris himantopus.

There are a number of species closely related to the calidrids which are included in the list.
The Stilt Sandpiper, previously Micropalama himantopus, has particular resemblances to the calidrid sandpipers, especially Curlew Sandpiper, and following confirmation of its close genetic relationship to that species, has now been reclassified as Calidris himantopus.
It is likely that future research will also result in either the incorporation of Aphriza, Limicola and Eurynorhynchus back into Calidris, or else the break-up of Calidris into several smaller genera (Crocethia for Sanderling, and Erolia for most of the small species).

It is the only member of the genus Limicola; some have proposed that it should be placed in the genus Erolia with the "stint" sandpipers, but more recent research (Thomas et al.
It is highly gregarious, and will form flocks with other calidrid waders, particularly Dunlins.
Despite its European breeding range, this species is rare on passage in western Europe, presumably because of the south-easterly migration route.

 04/05/00 -- Arctic warming signals dire straits for birds   (Site not responding. Last check: 2007-10-09)
With a global temperature increase of only 1.7 degrees by 2070, all of these birds would lose more than 50 percent of their habitat, the report notes.
The study forecasts that a 40 percent to 57 percent loss of tundra in the next 100 years may mean a loss of habitat for 5 million geese and 7.5 million calidrid waders.
While some scientists argue that the birds might adjust to their changing surroundings, others argue that many species such as waders, cannot physically adapt to brushy or tree-like habitats.

In particular, geese and Calidrid waders will be heavily affected as they breed almost entirely in tundra areas.
This suggests that a loss of 40 to 57 per cent of tundra would mean the loss of habitat for 4 to 5 million geese and abo ut 7.5 million Calidrid waders by the period 2070 to 2099.
Of course, the patterns of tundra loss will not be even, while the patterns of bird distribution within these habitat areas varies between species.}{\lang1031 }{\f0\lang1031 Two of the three globally threatened species among the studied Arctic water birds will be strongly affected.

 04/03/00 -- Climate change 'threatens Arctic birds'   (Site not responding. Last check: 2007-10-09)
As the climate warms, the treeline is expected to move further north, with forests replacing the tundra where millions of water birds breed.
The study says this could mean a loss of habitat by 2100 for between four and five million geese and 7.5 million Calidrid waders, birds of the sandpiper family.
The study, funded by the Worldwide Fund for Nature-UK, says one of the worst-affected species will be the red-breasted goose, which is already critically endangered.

We examine the potential selective importance of predation danger on the evolution of migration strategies of arctic-breeding calidrid sandpipers.
Adult calidrids truncate parental care for reasons not obviously related to levels of food abundance on the breeding areas or at migratory stopover sites, suggesting that a different trade-off occurs between providing additional care and adult survivorship.
Danger management may account for the these previously enigmatic features of calidrid migration strategies, and aspects of those of other birds.

The bill structure of this Calidrid is also thick and slightly decurved in exactly the way I expect from viewing thousands of Pectoral Sandpipers.
Leg color is a dull yellow, brightest when viewed from behind, duller yellow to greenish from in front.

The brightly-colored calidrid at the edge of a large flock of roosting Semipalmated Sandpipers stood out from the crowd, but after only a few minutes a jaeger flushed the entire flock and the observers were unable to relocate the bird.
The buffy orange on the face to lower breast indicated either C. ruficollis or minuta, and a band of streaks below the color suggested C. ruficollis, but the observers were conservative, given observation at 100 feet under poor light conditions.

They are postulated to be common among calidrid sandpipers, but comparative data are lacking.
Using high resolution microscopy, we measured number and size of sensory pits in Western Sandpipers, Least Sandpipers (Calidris minutilla) and Dunlin (Calidris alpina).

When one gains experience in watching shorebirds, another appeal is the challenge often present in their identification and the excitement of finding the rare wanderer.
Shorebirds vary from the boldly patterned like avocets and stilts to the subtlety of small Calidrid sandpipers (peeps or stints) with plumage variation by season and age.
Identification has become an intense study and there are now many books able to assist those drawn to the challenge.
