Chapala Birders Newsletter, January 2, 2021
174 Species Seen in December
The complete list appears at the end of this newsletter. Highlights this month include:
  • Four new species for the Lake Chapala area - a quite extraordinary happening - see section below.
  • Jules Evens saw a Black-chinned Hummingbird at his feeders in San Antonio Tlayacapan.
  • Nicola Cendron spotted a Long-billed Curlew on the dike during the Christmas Bird Count.
  • We went to the mountain above Mazamitla during the month and were amazed to see the fields and pine trees full of Pine Siskins (similar to female House Fiches, but with hints of yellow). It turns out that we are seeing the "biggest Pine Siskin irruption on record". Because pine cone seeds are in short supply in Canadian forests this winter, these birds are traveling way south for food.
Other notes from the month:
  • It wasn't easy putting together several small teams for the Christmas Bird Count while lacking some of our regular leaders, but with last-minutes appeals to friends and visitors, we did it.
  • We have decided to re-start our monthly birdwalks with small groups, masks and social distancing - see details below.
Four New Species for our Area
All of these new species were sighted by Nicola Cendron during our two Christmas Bird Counts:
  1. Rufous-capped Brushfinch on the Caracol Trail. This is a higher altitude bird which we normally see on the Sierra del Tigre at Concepción de Buenos Aires.
  2. Aztec Thrush on the Caracol Trail. This is an unusual, irruptive Mexican species.
  3. Olive Warbler, on the Caracol Trail. This is another species that we sometimes see at Concepción, two thousand feet above the lake.
  4. Swainson's Hawk (3 individuals) on the Dike at the east end of the lake. They were circling above a fire set to clear reeds for plowing a newly dried-up part of the lake. We believe they were looking to catch small animals escaping from the fire.
Christmas Bird Count Results
We fielded five small teams for the Ajijic area CBC on December 15. and just one team for the Dike area CBC on December 17.

In the Ajijic Circle we counted 9,462 birds of 128 species, and in the Dike circle 26,134 birds of 91 species. Combining the results, we saw 150 species. Once again we sent one team to hike to the top of the mountain. That team was unusually productive of new species.

We have looked closely at the results for each species, and once again we are unable to perceive any particular trends in the data for the last 15 years.
Featured Bird: Aztec Thrush
Male Aztec Thrush
  • The Aztec Thrush is an uncommon Mexican endemic species almost the size of an American Robin found in higher-altitude pine-oak forests of the Sierra Madre and Central Volcanic Belt. It is irruptive, moving in search of berries.
  • It is typically seen on the ground like other thrushes, often in small flocks. It is known to spend long periods sitting quite still and thus can be easily missed.
  • It eats insects on the forest floor but is particularly fond of berries when available.
  • The nest is a cup of grass and moss placed in the upper levels of trees. Both parents feed the hatchlings.
Bird-walks and Trips
We are proposing to start holding birdwalks again, but we will not go for breakfast at the end of each walk. Maximum attendance will be ten people. You must reserve a space by email at least 48 hours ahead of each birdwalk.

On Tuesday January 12, we will meet at 8.15 am at the entrance to Cristiania Park in Chapala. We should see an interesting selection of species in the park trees and on the shore of the lake. We will bird for about two hours. Wear face masks and practice social distancing. Reserve by email.
How to Get There: From Ajijic go to the traffic light at the main street of Chapala (Av. Madero), cross straight over and keep going straight for five blocks, turn left at the T intersection and park on the right.

On Friday January 21, we will meet at 8.15 a.m. at La Cristina on the west side of Ajijic. We will see some shore birds and some birds in the tall trees along the street. We will bird for about two hours. Wear face masks and practice social distancing. Reserve by email.
How to Get There: Drive about 2 mi (4km) west from Colon, look for signs for Hacienda La Cristina (near signs for Las Palmas, a bus stop and a vivero), turn down to the lake, and park close to the lake.

On Tuesday January 26, 8.30 am we will hold a birdwalk for people living in or near the Racquet Club. The meeting place and birding locations will be based on suggestions from those who want to attend. Please reserve by email with your suggestions. Face masks and social distancing will apply.

On Thursday January 28, 8.30 am we will hold a birdwalk for people living in or near Vista del Lago. The meeting place and birding locations will be based on suggestions from those who want to attend. Please reserve by email with your suggestions. Face masks and social distancing will apply.

Chapala Birders Newsletter, December 2, 2020
150 Species Seen in November
The complete list appears at the end of this newsletter.

This has been a busy birding month as we have ventured afield to Tapalpa, Mazamitla and Colima Volcano, all of these being trips that in normal times we would have invited others to join us.

Interesting sightings:
  • Brown Pelicans are being seen on Lake Cajititlan.
  • We went to the Dike at the east end of the lake with Nicola Cendron and Lizzy Martinez of Guadalajara, seeing Purple Gallinule and Long-billed Curlew.
  • John and Nicola hiked to the Oak Forest from the International School, seeing White-eared Hummingbird and ten species of warblers including Red-faced Warbler.
Another New Species for the Lake
Nicola Cendron was able to photograph a Brewer's Sparrow near the Pumping Station. This is a new species for Lake Chapala.

It is known as a nondescript sparrow of gray-brown color, which summers in the western U.S. and winters in western Mexico. In the summer it is the most common bird in sagebrush country. We are at the southern end of its winter range in Mexico.
Christmas Bird Count Details
Our Ajijic area Christmas Bird Count will be held on Tuesday Dec. 15. You should register by contacting John Keeling by email (chapalabirders@yahoo.com) or phone (376.766.1801 or 331.091.2136) giving us your name, phone, email, city of residence and donation preference - see below. John will assign you to a team. A typical team might have a maximum of 4 or 5 people in two cars. Usual start time is 8.00 am and counting normally continues until mid-day. We intend to follow government protocols for Covid control with small teams, compulsory masks and social distancing. This year there will not be a group dinner at the end of the day.

There is no fee for the Count, but in the past, members have encouraged me to ask for a donation towards the out-of pocket costs of Chapala Birders. These are for website hosting and newsletter mailing, which together cost $7,000 pesos per year.

The "Cienega" Christmas Bird count at the dike at the east end of the lake will be on Thursday Dec. 17. This will be a full-day affair leaving at 8.00 am and returning at 6.00 pm. Please let John know if you are interested in joining us.

Other Christmas Bird Counts near us:
  • The Guadalara Count will be held December 20.
  • The Primavera Forest Count will be on December 18.
History of the Christmas Bird Count
The tradition of a Christmas bird count started when Frank Chapman, an officer of the Audubon Society in New York, thought there must be a better way to celebrate the holiday season than spending the day in the great outdoors trying to shoot as many ducks and geese as you could, in competition with your buddies trying to beat your numbers. They proposed to look for as many birds of every kind that they could find in one day and to record totals. On Christmas Day 1900, 27 birders took part in the first Christmas Bird Count.

The tradition has been spreading across the Americas. Now more than 2,600 counts are conducted, including 58 in Mexico. More than 80,000 people participate annually in the event. The count area currently reporting the most species is the Yanayacu count in Ecuador with 491 species.
Featured Bird: Canyon Wren
Canyon Wren
The Canyon Wren is an elusive bird that sometimes sits on a prominent rock or roof line, waving its head from side to side while it sings a signature song of loud descending notes. It likes dry, rocky areas and is quite common in Ajijic.
  • It is found in Mexico, the western U.S. and British Columbia.
  • It is a resident in all locations, but sometimes relocates to lower altitudes in winter.
  • It has a very long bill to get at spiders and other insects in narrow crevices.
  • Pairs are monogamous, cooperating in nest building. The female incubates five eggs for 15 days. Both feed the nestlings for 15 days until they fledge. They may nest more than once in a summer.
Bird-walks and Trips
Unfortunately, we have not been scheduling any Bird-walks or any Birding Trips for Chapala Birders, due to the ongoing Covid restrictions.
