Chapala Birders Newsletter, September 2, 2024 | | | Sightings last Month
There were 118 species reported for the lake area in August. The complete list is shown at the end of this newsletter.
The first returning migrants were reported in the last 7 days: - Blue-gray Gnatcatcher was reported by Robert Cowan.
- Wilson's Warbler reported by Tom Bravo and Kate and Carl Anderson.
- Rufous Hummingbird was photographed by James Hatfield above Ajijjc.
- Ruby-throated Hummingbird was photographed by Jeff Morrow at the Raquet Club.
Earlier in the month: - David Stores photographed an American Dipper in the hills above Ajijic - see article below.
- Kate and Carl Anderson sighted Long-billed Curlew in Riberas del Pilar.
American Dipper - another first for our area
We hardly expect a Dipper in the intermittent streams above Ajijic, but David Stores found one. The range map shows that this species is resident here, in both the Western Sierra Madre and in the Trans-Volcanic Belt. National Geographic 'Birds of North America' also says: "casual vagrant well outside mapped range."
The American Dipper is a small dark gray bird with short wings designed for swimming. It feeds on aquatic insects on the bottom of fast-flowing streams and pools.
2nd Annual Lake Chapala Hawk Watch on Mezcala Mountain
Last year our birding friends from Guadalajara discovered a Hawk Migration Route along the mountains on the north side of the lake. We checked out different observation locations and confirmed that Mezcala Mountain provided the best viewing spot.
We intend to visit Mezcala Mountain frequently in September and October (see Trips below.) We hope our Guadalajara birders will visit on weekends. To whet your appetite, here is a summary of last year's sightings: |  | | Featured Bird: Mexican Duck | | | A female Mexican Duck showing the Field Marks: dark brown body, blue speculum (wing patch), brown tail; also orange legs, dark crown and eyeline. - The female has a yellow-orange bill, while the male has a yellow-green bill.
- This duck is generally vegetarian, preferring young shoots of aquatic plants, grasses and seeds.
| | - The Mexican Duck occurs primarily in central and northern Mexico, with small populations in New Mexico and Colorado. Sexes are similar, both appearing like a female Mallard.
- It is genetically related to the American Black Duck and the Mallard.
- Because Mallards hybridize with many other ducks, and Mallard x Mexican hybrids are fertile, this has created disagreement among taxonomists as to whether this should be a species or a sub-species.
- The Mexican Duck breeds in the rainy season, making a well-hidden nest in dense grass some 200m (500 ft) from water.
- 2 to 10 eggs are incubated for 26 days, all hatching together, so that the ducklings can be taken to water within a day or so.
| | Upcoming Bird Walks and Trips | | | 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. Note that we will try to limit most car trips to three vehicles and 14 people because larger convoys are hard to manage when trying to stop on country roads to look at the birds. If you are being given a ride, we suggest you make a contribution to your driver for gas and tolls (perhaps $150 pesos for a half day outing, $300 pesos for a day trip).
On Friday September 6, we will meet at 8.00 am at the trail head to hike a mile up the Allen Lloyd Trail which has lots of underbrush in which birds love to hide. Expect to see Blue Mockingbird and hear the Happy Wren. At about 10.00 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 (1km) from the traffic light at Walmart, then turn left (carefully) as you would for the new hospital (Ribera Medical Center), double back and drive up the left side of the hospital, keep going uphill another half mile, and park on the only street to your left.
On Thursday September 12, we will meet at 8.00 am at the "Sculpture" at the only traffic light in La Floresta, (south-east corner), leaving immediately for the Sierra de Tapalpa (90 minutes away). We will bird from 9.30 till 12.30. 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. At 1.00 pm we will end up in Tapalpa to have lunch at a restaurant overlooking the square. Expect to be back about 4.00 pm. You must reserve - email John at chapalabirders@yahoo.com at least 2 days ahead indicating if you can bring a vehicle and can take others, or you would like to be a passenger. (We don't always have enough cars).
HAWK WATCH: On Tuesday September 24, we will meet at 8.00 am at the Sculpture at the only traffic light in La Floresta (south-east corner, opposite Restaurant Pranzo) leaving immediately for Mezcala Mountain (60 minutes drive). We will park and then walk the one-mile (1.5 km) trail to the observation point. Bring snacks and sandwiches for lunch. We will return to Ajijic by 3.00 pm. Other pick-up points can be arranged between Ajijic and Mezcala. If you plan on going, you must email John at chapalabirders@yahoo.com at least 2 days ahead indicating if you can bring a vehicle and can take passengers, or you would like to be a passenger. High-clearance, all wheel drive vehicles with off-road tires are recommended for the ascent.

We were surprised at the number of different heron and egret species that were feeding young on nests in the trees. Typically the foliage hides some of the species. We saw 45 species including Rufous-backed Robin, Black-backed Oriole, Little Blue Heron, Fulvous Wistling Duck, Black-bellied Whistling Duck, Caspian Tern and Forster's Tern.
On August 16, we had ten keen birders out for the Rosa Amarilla Loop on the plateau above the south side of the lake. We observed Wilson's Phalarope, Chihuahuan Meadowlark, Ruddy Duck, White-tailed Hawk, Sinaloa Wren and Black Phoebe out of a total of 53 species. | | | Here are the 118 species observed around Lake Chapala in August:

What is the "Lake Chapala Area"? We define it as the whole area of the lake plus all land within 15km (or 7 miles) from the edge of the lake. | | | Lake Chapala Birders is an informal group of bird observers led by John and Rosemary Keeling.
Illustrated color folders showing our common birds are available for $200 pesos at Diane Pearl's Gallery, 11 am to 4 pm, Santa Margarita #23, at the east end of Riberas del Pilar. Also available from John Keeling on bird walks.
We like to hear of bird sightings at: chapalabirders@yahoo.com.
