Chapala Birders May Newsletter

120  Species Sighted Last Month
The complete list of April sightings is shown at the end of this newsletter.
John Keeling in currently helping with the translation of the excellent Lake Chapala birding app, which is available free in the Spanish language version from both Android and Apple App Stores ('Aves de Chapala').

Interesting sightings last month:
  • George Webb reported sighting a Green Violetear at his hummingbird feeder on the laksehore west of Ajijic. This species is only rarely seen here. We have previously seen one at Las Trojes.
  • We continue to be impressed by birds which stick to very specific 'niche' locations. For instance the Western Kingbirds seen this winter on the Allen Lloyd trail can be still be seen there, but in reduced numbers; and several Orchard Orioles can now be seen at the pier in Jocotepec exactly where we have sighted one or two of them in prior years.
  • We received a photo of a fledgling green and blue bird which had landed on a terrace, and was not yet keen on practicing the art of flying. It was an Elegant Euphonia.
  • Local birder Carlos Cuevas was part of a small group of University of Guadalajara bird banders who went to La Cañada during the Easter break to band bats at dusk on the Los Sabinos creek which is a State Protected Area. An unexpected catch was the Green Kingfisher shown below.
Green Kingfisher
This male Green Kingfisher was photographed by Carlo Cuevas after being caught in mist nets at dusk on Los Sabinos Creek at the village of La Cañada.
  • The Green Kingfisher is a very small bird which we see from time to time at the east end of Lake Chapala.
  • While the male has a red breast, the female has a white breast with green spots.
  • It is a non-migratory resident with several subspecies which cover the territory from Southern Texas to Southern Brasil.
  • Found at streams and ponds, it eats small fish, crustaceans and water insects.
  • It is easily missed because it perches very low in vegetation over water.
  • It typically nests in a horizontal, meter-long tunnel in a stream bank.
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 Wednesday May 10 we will meet at 8.30am at the Jocotepec Malecon.
We will observe water birds at the pier and explore the park for wrens and woodpeckers. At 10.15 we will go to a local restaurant for breakfast and complete the bird list.
To Get There: Driving from Ajijic, close to Jocotepec you encounter a left curve followed by serious 'topes', then a curve to the right with an OXXO on the left side of the curve. Turn left before or after the OXXO, proceed to the shore, and park.


On Monday May 22 we will meet to carpool at Donas Donuts at 8.00am, leaving immediately for Lake Atotonilco at Villa Corona (a 60 minute drive).
We expect to see Roseate Spoonbills and Wood Storks there, as well as various other lake and marsh birds. Take your own refreshments (there is no good place to have breakfast). We will be back in Ajijic about 12.30. If you plan to go please email chapalabirders@yahoo.com indicating whether you can bring a vehicle, to help us balance the car pool.

Bird Walk & Trip Reports
On April 7 five people came out for the hike up the Allen Lloyd trail. Particpants were thrilled to see two Squirrel Cuckoos putting on a display. An Orange-billed Nightingale Thrush made itself visible, while a Russet-crowned Motmot was identifiable only by call. We observed 34 species in total.

On April 19 we had 17 birders out at Lake Cajititlan,
where we saw 52 species, including Yellow-headed Blackbird, Black-bellied Whistling Duck, Black-necked Stilt, White-tailed Kite, immature Gray Hawk, and Loggerhead Shrike.

April Newsletter



Chapala Birders Newsletter April 2, 2017
151 Species Sighted Last Month
This is a high number of species for March in recent years, though figures used to be better - our highest March count was 166 species in 2011. The complete list of March sightings is shown at the end of this newsletter.

Interesting sightings last month:
  • On the Allen Lloyd Trail we saw Elegant Euphonia, which has been  uncommon in the last year.
  • While working on the Birding App for Lake Chapala, we listened to the recorded call of the Northern Beardless Tyrannulet, and heard it in Ajijic within a week. It is an under-reported bird - see below.
  • Visiting Lake Cajititlan marsh we saw a Merlin in a tall dead tree at the lake edge for a sufficient time to establish that it was not a Peregrine Falcon nor an American Kestrel.
  • Hiking with Duncan Poole and Brian Lewis up the arroyo above Zapotitan near Jocotepec, we encountered both Magnificent and White-eared Hummingbirds at 1,500 feet above the lake level.
Northern Beardless Tyrannulet
Northern Beardless Tyrannulet as seen last month in Ajijic
  • This is our very smallest flycatcher, inhabiting scrub, open areas and woodlands from Mexico to Costa Rica. It is known to be elusive (and under-reported), often sitting in a tree not moving. Most times you will only know it is there from its call, either a descending 'peej-peej-peej-peej' (weaker than a Canyon Wren call) or 'tiddlydoo'.
  • It has an upright posture, a drab gray-brown color, with the mandible partially flesh-colored, often raising its crest into a dome shape.
  • It prefers to pick small insects from trees and leaves, occasionally flying out to capture flying insects, and eats berries in season.
  • The nest is built in trees at mid-levels hidden between clumps of other growths like air-plants or mistletoe, with a side entrance.
  • It is called 'beardless' because it lacks the little bristles at the base of the bill seen on most flycatchers.
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 April 7 we will meet at 8.00am to walk 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 possibly a Squirrel Cuckoo. 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 Wednesday April 19 we will meet at 8.00am to carpool at Donas Donuts departing immediately for Lake Cajititlan (30 minutes drive). We will see a variety of marsh and lake birds. At about 10.15 we will go to Las Delicias restaurant in Chapala for breakfast and complete the bird list. If you plan on going, email John: Chapalabirders@yahoo.com indicating whether or not you will have a car.

Results of the February 17-20 "Great Backyard Bird Count".
This year four of our local birders submitted lists during the four-day count period. Worldwide, more than 200,000 people submitted reports on 5,940 species. The specie with the highest count was the Snow Goose with 4.7 million individuals reported.

The country reporting the most species was India with 801 species,  followed closely in second place by Mexico with 774 species.

It was observed that as a result of an unusually warm winter this year in the U.S., many birds started their northward migration more than two weeks earlier than normal, particularly Tree Swallows, Killdeer, Red-winged Blackbirds and Common Grackles.
Bird Walk & Trip Reports
On March 9 four of us went to the Rio Verde canyon near Acatic. The hot pools were better than ever for swimming. We saw Gila Woodpecker, Black-throated Magpie Jay, Green Kingfisher, Common Black Hawk and Squirrel Cuckoo from a total 39 species sighted.

On March 15 we had 14 people out at El Bajio on the west side of Ajijic. We saw an incredible 75 species, including Black-necked Stilt, Summer Tanager, Plumbeous Vireo, Gadwall, American Wigeon, Yellow-breasted Chat, White-tailed Kite, Tri-colored Heron, Berylline Hummingbird and Rufous Hummingbird.

On March 27 a group of seven birders went to the Rosa Amarilla Loop on the 'El Tigre' plateau. After a slow start we accumulated a list of 66 species including Gray Hawk, American Avocet, Lesser Yellowlegs, Say's Phoebe, Stripe-headed Sparrow, Northern Mockingbird and a flock of Brown-headed Cowbirds hiding in a bush making sounds exactly like water flowing into a pool.
