Another New Species for Lake Chapala - Limpkin


Last month, during their monthly visit to the Dike at the East end of the lake, John and Rosemary observed two Limpkins near the village of La Palma. They were feeding in shallow water on flooded corn fields. This species has never been reported at Lake Chapala before. They are larger than Ibises, generally brown, with characteristic white spots.

The range of this species is slowly expanding northwards. In his 1995 reference book, Steve Howell shows the traditional range in Mexico as being the coastal regions of Southern Mexico. Since then the bird has been increasingly reported along the coasts of Colima, Jalisco and Nayarit. In 2006, a University of Guadalajara paper reported sightings in the interior of Jalisco in the area of Autlan. This year Limpkins have been sighted at Presa la Vega just 50 kilometers west of Lake Chapala. They inhabit shallow, fresh water areas. They prefer to eat snails, but will also eat frogs, small crustacians and seeds.
Stilt Sandpiper
Stilt Sandpiper in winter plumage as seen at Lake Chapala in April on migration.

The Stilt Sandpiper - is a long-distance migrant, breeding in the high Arctic and wintering mainly in South America, also in central Mexico and Central America. It is generally seen in shallow, muddy, fresh water pools and marshes.
- Eggs are laid on the tundra at the time of the Arctic spring in early June. The female sits the eggs at night, and the male during the day. After three weeks the eggs hatch. The chicks leave the nest almost immediately, finding all their own food. The female leaves after a week, and the male after two weeks as the chicks are starting to fly. The adults fly south in August making a mad dash for South America, and the juveniles leave in September taking their time on the route.
- While the breeding plumage is much darker, heavily marked with black and brown spots, the winter plumage is quite plain.
- In winter the Stilt Sandpiper is easily mistaken for the Long-billed Dowitcher when feeding, and is easly confused with the Lesser Yellowlegs when walking. Look for the curvature of the bill, and the white supercilium.
Upcoming Trips and Bird Walks
Our bird walks are open to all those interested in birds, both beginners and experienced birders. Just bring binoculars. We always have knowledgeable birders on hand to identify the species. We will try to limit day trips to four vehicles, as larger convoys are less manageable. If you are being given a ride, please make a contribution to gas and tolls (perhaps 50-100 pesos for a half day outing, 150-200 for a day trip).
 
On Monday June 12, we will meet at 8.00 am to walk the one-mile long Allen Lloyd Trail which has lots of underbrush in which birds love to hide. Expect to see Stripe-headed Sparrow and Groove-billed Ani and hear the Happy Wren and Orange-billed Nightingale Thrush. At about 10.15 we will head to Cafe Negro restaurant for breakfast and complete the bird list.
How to get to the trail head: Drive up the Libramiento a half mile from the traffic light at Walmart, and park on the north side of the road across from the El Dorado Condominium tower.

On Friday June 21, we will meet at 8.00 am at Donas Donuts to car pool, leaving immediately for the Sierra de Tapalpa (90 minutes away). We will bird from 9.30 till 12.30 and have lunch in the town of Tapalpa and complete the bird list. We expect to see higher altitude birds such as Acorn Woodpecker and Slate-throated Redstart and if we are lucky Trans-volcanic Jay. Bring your own refreshments for the morning. We will be back about 5.00 pm. If you plan on going, please email John at chapalabirders@yahoo.com at least 48 hours ahead of time saying whether you can bring a vehicle.
Bird Walk and Trip Reports
On May 6 we had a small group to bird the lakshore road from the Old Train Station to the Pumping Station. We saw uncommon birds such as Marbled Godwit and Semipalmated Plover, as well as American Avocet, Mourning Dove, Black-backed Oriole and Tri-colored Heron out of a total of 53 species.


On May 17 we travelled to the Rosa Amarilla Loop on the plateau above the south shore. We saw an impressive 64 species including Western Wood Pewee, Say's Phoebe, four Wren species - Spotted, Happy, Bewick's and Canyon, as well as Eastern Bluebird, and Botteri's Sparrow which comes to the grass fields of this area every summer.
