Chapala Birders Newsletter January 2, 2018
168 Species Sighted Last Month - a Record
The complete list of December sightings is shown at the end of this newsletter.

Interesting sightings last month:

-  After two pygmy owl sightings in November, we received a photo  from Liz Durham of an owl that flew into a closed window of her house at dusk. (She lives on the west side of Ajijic). She put the confused owl on a towel, photographed it, and later it flew away. We have identified it as a Mountain Pygmy owl.
-  Brian Lewis continued his trend of finding new locations of the rare White-throated Flycatcher for the Christmas Bird Count - this time at the reed beds of Cristiania Park opposite the restaurants in Chapala.
-  John Roynon observed the uncommon Least Bittern in a new location - this time at the reed beds of the malecon in San Antonio Tlayacapan.

New Species for the Lake Chapala List

After the Christmas Bird Count, John and Rosemary went birding on the Allen Lloyd Trail, where there is a 'sweet spot' about 200 meters long which includes trees with berries and creeper-covered undergrowth. Unexpectedly a very small bird popped up on top of some tall plants. It had an unusual yellow-green body color, and unique yellow 'spectacles' on the face. It was a White-eyed vireo - a first for Lake Chapala. Read the description below.
Report on the 2017  Christmas Bird Count
This year we chose to bring in new blood to the team leadership - our regular leaders have been leaders so many times, they can do it in their sleep. Our new leaders were: Lois Lewis, Rosemary Keeling, Francis Riedelberger, Rudy Neustaedter, Mary Kiely, Mary Paston and Duncan Poole. They did a great job.

We recorded 126 species and 40,879 individual birds, which included 30,000 Yellow-headed Blackbirds. Looking at the results we can see no clrear overall trends. Figures for numbers of birds were essentially 'average', lying within the range of figures from the previous eleven years. Only Eurasian Collared Doves are steadily increasing, having first arrived here in 2006. We did report a bigger species total this time primarly because one team, for the first time, went up to the ridge, 8,000 feet above sea level, and descended through the oak forest on the other side, recording nine species, such as Hermit Warbler and Acorn Woodpecker, not previously recorded here on the CBC.
White-eyed Vireo
White-eyed Vireo as seen on the Allen LLoyd Trail.

Species details:

-  The White-eyed Vireo is a very small songbird that breeds in the eastern and south eastern US, and spends the winter on the east side of Mexico, in the Yucatan, and in the Carribean. It is only rarely seen in Jalisco.
-  It is a secretive bird that hides in dense underbrush, swampy thickets and forest edges. It avoids urban areas.
-  On the summer nesting grounds, the male sings incessantly to protect its territory. Each bird is said to have a repertory of a dozen distinct songs. It is estimated that half of all nests are targets of parasitism by Brown-headed Cowbirds that lay their eggs in the Vireo nests. When this occurrs, the vireo chicks do not usually survive the competition from the bigger cowbird chick.
-  It feeds on many different small insects including ants, wasps, beetles, scale insects and small snails. In winter the insect diet is supplemented by eating small berries.
Upcoming Trips and Bird Walks
Our bird walks are open to all those interested in birds, both beginners and experienced birders. Just bring binoculars and show up. We always have knowledgeable birders on hand to identify the species. If you are being given a ride, please make a contribution to gas and tolls (perhaps 50-100 pesos for a half day outing, 100-200 for a day trip).

On Friday January 12 we will meet 8.00 am at the Allen Lloyd Trail which follows a mile-long arroyo with lots of underbrush in which birds love to hide. It remains our most interesting local bird walk. Expect to see Golden-fronted Woodpecker, stripe-headed Sparrow and Blue Mockingbird. At 10.15 we will head to Sunrise restaurant for breakfast and complete the birdlist. 
How to Get There: Drive up the Libramiento a half mile and park on the north side of the road opposite El Dorado Condominium.

On Monday January 22 we will meet at 8.00 am at Donas Donuts, 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 ahead of time saying whether you can bring a vehicle.

On Wednesday January 31 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 tall trees and on the shore of the lake. At about 10.30 we will go to 'La Palapa de Don Juan' for breakfast and complete the bird list.
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.
Bird Walk & Trip Reports
On December 8 we had 15 birders out at the Jocotepec Malecon Park. We managed to see 48 species including Common Gallinule, Least Grebe, Sora, Yellow Warbler, Marsh Wren, Common Yellowthroat, and a very nice American Bittern pretending to be a reed.

On December 27 we had six vehicles at Villa Corona on Lake Atotonilco. The lake edge was teeming with birds including American Pipit, Wilson's Snipe, both Clark's and Western Grebe, as well as groups of Snow Geese, Roseate Spoonbills, Wood Storks, and large numbers of American White Pelicans. We saw over 70 species.
