Chapala Birders Newsletter October 2, 2019
    121 Species sighted last month around the Lake
The complete list of species for last month is shown at the end of this newsletter.

This is the month that the Rufous Hummingbirds come down from the western US and Canada through Jalisco on migration. We hope to see them when we visit Tapalpa, or other higher altitude locations like Rosa Amarilla and Concepcion.
 
Interesting sightings last month:
- A Sharp-shinned Hawk was photographed at Vista del Lago after it hit a window. It flew off after a few minutes.
- Stan and Darnell Dunn observed Yellow-throated Warblers in their back yard in La Floresta. These are pretty warblers that we sometimes see here as they migrate south.
Happy Wren
   A Happy Wren seen at Ajijic


The Happy Wren:
-  Is an endemic Mexican bird found in the lowlands and mountains on the west side of the country from Sinaloa to Oaxaca.
- It is a very shy bird preferring vine covered understory. It is much more often heard than seen.
-  It breeds in May and June building a 'retort-shaped' nest of dry plant material, consisting of a nest bag with an entrance tunnel that curls in an arc downwards from the top of the bag. The bird flies vertically upwards to enter the tunnel.
-  It eats mainly insects such as spiders, beetles and caterpillars.
-  It is most famous for it's habit of precision duetting with its partner so it sounds as if one bird is singing. Each wren has a sex-specific repertoire of at least 40 phrases. When the female starts singing the male will immediately start in unison using coded phrases. Different phrases are used to signal aggression to an intruder.
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. Please note that we will try to limit car trips to four vehicles because larger convoys are less manageable 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 50-100 pesos for a half day outing, 150-200 for a day trip).
 
On Wednesday October 9, we will meet a 8.00 am at Donas Donuts to carpool, leaving immediately for Las Trojes (one hour away), to hike the Horizontal Oak Forest Trail. We hike to the edge of the hidden valley (3-hours hiking uphill, 2-hours back). Don't expect very many birds, but the hike is very pleasant and we may see the Red-faced Warbler. We will be back about 4.00 pm. Bring refreshments and sandwiches for lunch at noon at the top. If you plan on going, please email John at chapalabirders@yahoo.com 48 hours ahead of time saying whether you can bring a vehicle, to help in carpool planning.

On Friday October 18, we will meet at 8.00 am at the Old Train Station in Chapala, proceeding immediately to bird various shore spots along the road east of Chapala, and the Pumping Station.
This will cover a wide range of habitats. At 10.15 we will head to La Palapa de Don Juan restaurant for breakfast and complete the birdlist. If you need a ride (on the trip, or to the train station) please email John at chapalabirders@yahoo.com ahead of time. The train station is on the Lakeshore road just east of Cristiania Park.

On Monday October 28, we will carpool at Donas Donuts at 8.00 am, 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 48 hours ahead of time saying whether you can bring a vehicle, to help in carpool planning.
Bird Walk and Trip Reports
On September 9 we went to the Rosa Amarilla Loop on the plateau with nine birders. We observed Northern Bobwhite, Northern Jacana, Orchard Oriole, Wood Stork, Gray-crowned Yellowthroat, American Avocet and five Lesser Roadrunners. The total count was 53 species.

On September 18 we were joined by seven birders on the Allen Lloyd Trail. Birding was slow - we observed only 38 species. These included Gray-Silky Flycatcher, Dusky-capped Flycatcher, Western Wood Pewee, and we heard the calls of the Happy Wren, Russet-crowned Motmot and the Northern Beardless Tyrannulet.
