Wader Heaven at La Llave

A fine selection of waders was to be had at La Llave on Saturday morning.  Water levels are low at this reservoir as well, but the large expanses of exposed muds held some really interesting species.

As well as the gorgeous Wilson's Phalaropes pictured in the last post, I had the following (along with some notes about each one based on my observations).

American Golden Plover - 1.  A rare bird in Queretaro, and a first for me.

 2. Black-bellied Plover. 1. Again, a rarity in Queretaro, normally confined to the coasts in Mexico.

3. Semipalmated Plover. 4.  A good number of this coastal plover.

4.  Killdeer. Common.  Starting to get very territorial.

5. Spotted Sandpiper.  A lot, including two very territorial males (see below).  Do they breed round here?

6. Least Sandpiper.  Several hundred.  Common winter visitor.

7. Baird's Sandpiper. 3.  Much more common in autumn, where they can be found in their 1000s.  I haven't recorded them previously this spring, though.

 7. Pectoral Sandpiper. 6.  A good number of a bird only found here during passage.

8. Stilt Sandpiper. 5.  Winters in small numbers and more frequent in passage.

9. Long-billed Dowitcher.  >1000.  Huge numbers of this elegant wader, almost all of them  in breeding plumage as well.

10. Black-necked Stilt.  Quite common year round.

11.  Avocet. 5. Seem to be more prominent on passage.

12. Lesser Yellowlegs. c.20.  Seem to be many here and at Centenario during spring.

13. Greater Yellowlegs. 4

14. Wilson's Phalaropes. 200.

Not  a bad haul of waders all in all.  I'll try and get back there before the season is over, because it will probably get very quiet during the summer.

Non-wader highlights included hordes of White-throated Swifts, 1 Crested Caracara, 1 Northern Harrier, decent variety of ducks still (inc. American Wigeon, Gadwall, Pintail, all 3 Teals, and 1 Fulvous Whistler), Common Yellowthroat, Barn, Cliff and Bank Swallows. and plenty of other common stuff.
