Chapala Birders Newsletter October 2, 2018
119 Species Sighted Last Month 
The complete list of species seen around Lake Chapala is shown at the end of the newsletter.
October is the month for the arrival of all the migrating birds that will spend the winter here in Jalisco. A few early ones have already arrived. Studies show that these birds are now migrating south later in the fall, and going north earlier in the spring, by about a week in each case.
Interesting sightings last month included:
- The Ferruginous Pygmy Owl that everyone on the Jocotepec Bird Walk saw in a silk-oak tree. 
- The Osprey that was seen on the Rosa Amarilla Bird Trip, at the dam where it has been seen several times this year. 
- The unusual Slate-throated Redstart seen on the Las Trojes Bird Walk.  
- The Red-faced warblers seen on the Las Trojes Bird Walk in exactly the same place we usually see them fall and spring.  
- The Roseate Spoonbill and Wilson's Phalarope seen on the Lake Cajititlan Bird Walk.
Osprey
  An Osprey as seen at Rosa Amarilla last month.

The Osprey weighs three pounds, with a 6-ft wingspan, and is unusual in a number of ways:-  It it one of few birds to have achieved a worldwide distribution.
-  It feeds almost entirely on fish, having adaptations for fishing.
-  It sees in the UV range to better see fish colors under water.
-  The third front toe can be rotated to act as a second rear toe.
-  The claws are highly curved and have barbs to improve grip.
-  It has closeable nostrils for diving 3 ft below the surface.
-  In a dive the head is poked forward between the legs for less drag.
-  It has extra shoulder rotation to allow the wings to perform a vertical takeoff when it comes to the surface with a fish.
Go Birding on Saturday October 6
The Cornell Lab is introducing "October Big Day" to promote birding and to promote the use of e-Bird for recording your sightings. This is intended to supplement the very successful 'Global Big Day' which is held in May of each year.
A Big Day is where serious birders get up really early to visit a series of good birding sites continuing until after sunset, to find the greatest number of species between midnight and midnight. We encourage you to take part this Saturday by going birding somewhere interesting for an hour or more and then reporting your list to eBird.
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, 100-200 for a day trip).
 
On Friday October 5, we will carpool at Donas Donuts at 8.00 am, leaving immediately for Villa Corona (60 minutes drive). We expect to see various beach birds such as Red-winged Blackbird, White-faced Ibis, and Roseate Spoonbill. Bring your own mid-morning refreshments. There is no breakfast or lunch stop. We will be back in Ajijic by about 1.30 pm. If you plan on going, please email John at chapalabirders@yahoo.com at least 48 hours ahead of time saying whether you will bring a vehicle, to help in carpool planning. (We don't always have enough cars).

On Wednesday October 17, we will meet at 8.00 am to carpool at Donas Donuts leaving immediately for the Cajititlan Marsh (30 minutes drive)). We expect to see a variety of marsh and lake birds such as Black-necked Stilt, American Avocet, and perhaps a Wood Stork. At about 10.15 we will go Las Delicias restaurant in Chapala for breakfast and complete the bird list. If you plan on going, email John: Chapalabirders@yahoo.com at least 24 hours ahead of time indicating whether or not you will have a car. (We don't always have enough cars).

On Monday October 29, we will meet a 8.00 am to walk the Allen Lloyd Trail which follows a mile-long arroyo with lots of underbrush in which birds love to hide. Expect to see Stripe-headed Sparrow, Greater Pewee and Groove-billed Ani. At 10.15 we will head to Cafe Negro restaurant for breakfast.
How to Get There: 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.
Bird Walk and Trip Reports
On September 10, we had 14 people on the trip to the Sierra de Tapalpa which is at 7,500 ft. We saw Gray Silky Flycatcher, Eastern Bluebird, Striped Sparrow, the unusual Black-headed Siskin and five hummingbird species - Berylline, Ruby-throated, Rufous, Rivoli's and White-eared, for a total of 40 species.

On September 19, twelve birders joined us at the Jocotepec Malecon Park where the highlight was sighting the newly-resident Ferruginous Pygmy Owl perched in a silk-oak tree. We saw 46 species including Orchard Oriole, Tri-clolored Heron, Cinnamon-rumped Seedeater and eight American White Pelicans which are part of the group of one-year-olds that spent the summer here. The breeding pelicans will come down this month.

On September 28, eight keen birders made the hike up to 7,500 feet along the "horizontal oak forest trail" at Las Trojes. We saw Greater Pewee, Hermit Thrush, Black and White Warber, Wilson's Warbler, Townsend's Warbler, Red-faced Warbler, Painted Redstart and an unexpected Slate-throated Redstart, out of a total of 28 species.

Chapala Birders Newsletter September 2, 2018
103 Species Sighted Last Month 
The complete list of species seen around Lake Chapala is shown at the end of the newsletter.
Carlo Cuevas encountered a Ferruginous Pygmy Owl at the Jocotepec malecon and was able to take a video of it calling. Stan Dunn has been hearing one calling every evening and morning in La Floresta. This owl is quite unusual here at Lake Chapala. 
We all had a big suprise on the August 6 trip to Villa Corona. Lake Atotonilco was covered with thousands of birds. Rainfall has been poor this summer and the lake level is so low many birds were standing in the shallow water a mile away in the center of the lake (see trip report below). 
 Ferruginous Pygmy Owl
  Ferruginous Pygmy Owl as seen at the Jocotepec malecon in August.

Species details:


- This is a tiny owl only 5.5 inches long. You can hold it in the palm of your hand. It comes in two colors, the brown morph as in the photo, and the rufous morph which is almost orange in color. It has two black simulated eye spots on the back of its head.
- It is common throughout Mexico, Central America and most of the South American continent. It likes semi-open wooded habitats, and does not migrate.
- The claws are especially large for its size. The prefered food is lizards, but it also eats large insects, small birds and small mammals.
- It is a cavity nester, the female sitting on the eggs for 28 days fed by the male, then both parents feed the chicks for another 28 days until they fledge. These periods are double the equivant times for songbirds.
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. 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 Monday September 10, 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.

On Wednesday September 19, we will meet at 8.30 am at the Malecon Park in Jocotepec. We expect to see a variety of shore birds such as Northern Jacana, as well as other species in the tall trees of the park, such as Golden-fronted Woodpecker. At about 10.30 we will head to Frida's nearby for breakfast
How to Get There: From Ajijic go through San Juan Cosala and after El Chante you wiil encounter a long curve to the left, followed by major topes, followed by a long curve to the right. Take a left exit at the beginning, or end, of this last curve. Proceed towards the lake and park in the malecon parking lot.

On Friday September 28, 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.
Bird Walk and Trip Reports
On August 6, we had a keen and optimistic group of 19 birders out at Villa Corona on Lake Atotonilco. We were amazed by the thousands of birds visible on the lake. The water level is now so low that long-legged water birds could be seen even in the center of the lake. We saw exceptionally large numbers of American Avocets, White-faced Ibis, Black-necked Stilt, and Roseate Spoonbill. Also an uncommon White Ibis and a Semipalmated Plover.

On August 17, we had 19 people to travel the Rosa Amarilla Loop. We saw Osprey, Red-tailed Hawk, White-tailed Hawk, Botteri's Sparrow, also 80 American White Pelican (these stayed in the region for the summer), and a hundred Wood Storks, including a sighting of a juvenile Wood Stork in the top of a tree. Everyone commented at the end on what a marvelous trip it was.
