New Species sighted at Lake Chapala in March
Visiting birder Nicola Cendron from Mexico City was birding on the lake edge near the Pumping Station last month when he observed a Least Tern which is a species we have not recorded here before.

It is interesting to note that there have been a number of sightings of this species at Villa Corona on Lake Atontonilco, which is only 30km west of Lake Chapala.

See 'Featured Bird' below.
179 Species sighted around the Lake in March
This is an unprecedented number of species for March - two species more than we had in December which is normally the biggest month. We can attribute this to the quality and perseverance of our resident birders and our visiting birders.

Interesting observations last month:

- The Caracol Trail (accessed from the International School Road) is a current hotspot. Nicola Cendron and Jules Evens saw White-eared Hummingbirds and heard Mountain Pygmy Owl there.

- On the Las Trojes Oak Forest Trail to Chupinaya John Keeling and Duncan Poole saw Flame-colored Tanager and heard Elegant Trogon.

- Don Bell reported Black-chinned Hummingbird and Ruby-throated Hummingbird in his garden in west Ajijic.
Featured Bird:   Least Tern
 Least Tern in breeding plumage. Note yellow bill and white forehead.

The Least Tern is the smallest of the terns in North America. It's body is only nine inches long, but it has long wings with a 21 inch wingspan.

- Though it is found around the world, in the Americas its range is from the Great Lakes to Argentina.

- It is migratory, passing through our area in March and April to its breeding grounds further north.

- It likes sandy beaches beside lakes, rivers and oceans. The nest is a shallow "scrape" in the sand holding 2 to 4 eggs. Incubation takes 21 days; the young can walk around within 3 days and fly at three weeks, but are fed by the parents for two months.

- It flies low over the water with rapid wing-beats and a graceful flight. It will hover and dive into the water to catch small fish sometimes several feet below the surface. It will also eat marine worms, insects and small molluscs.
Upcoming Trips and Bird Walks
Unfortunately, we will not have any bird walks or bird trips this month, due to the official 'Stay-at-Home' orders.
Bird Walk and Trip Reports
On March 6, we went to the Cajititlan Marsh with seven attendees who enjoyed seeing 63 species which included Marsh Wren, Common Yellowthroat, White-throated Flycatcher, Crested Caracara, Yellow-headed Blackbird, and 500 American White Pelicans.

On March 16, there were twenty birders out for the easy hike up the Allen Lloyd Trail. We observed Golden Vireo, Happy Wren, Cinnamon-rumped Seedeater, Blue Mockingbird, Squirrel Cuckoo, Bushtit, Sharp-shinned Hawk and Cooper's Hawk, out of a total of 57 species.

  153 Species sighted around the Lake in February
Squirrel Cuckoos and Russet-crowned Motmots have just returned to our hills to find mates and build nests.

This is the month when our migrant birds start leaving Jalisco on their way to their northern breeding grounds. An exception is the American White Pelican which is a powerful flyer and doesn't need to stop so much on the way. It leaves in late April in order to arrive in the northern US states and southern Canada in May when the ice on the lakes is melting.

Interesting sightings this month:
- At the breakfast after the Chapala East Bird Trip we spotted a Western Grebe (unusual at Lake Chapala).
- Don Bell reported seeing a Ruby-throated Hummingbird on its way back up north.
- John Roynon reported a Brown-backed Solitaire singing in the hills above Ajijic.
- Laura Dangerfield saw a Yellow-breasted Chat at the San Antonio malecon.
- Jules Evens reported seeing Black-chinned Hummingbird and Grasshopper Sparrow.
Featured Bird:   Broad-billed Hummingbird

The Broad-billed Humminbird is one of our two commonest species of Hummingbird at Lake Chapala (the other is the Violet-crowned).

- The females and immatures have a greenish back, with gray throat and underparts. Immatures may have a black bill.

- Its range is primarly northern and central Mexico, though some birds are seen in Arizona in the summer.

- Their diet is a mixture of nectar taken from trumpet-shaped flowers and insects which are caught on the wing or gleaned from leaves.

- They breed from January to September. The female builds a tiny nest typically attached to the end of a trailing branch or vine. She lays two eggs and incubates them for two weeks while the male guards the territory from a point close by.
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 Friday March 6, we will meet at 8.00 am to carpool behind Black Coffee, in the Laguna Mall parking area, 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, Snowy Egret, and perhaps American Avocet. At about 10.15 we will go La Palapa de Don Juan restaurant in Chapala for breakfast and complete the bird list. If you plan on going, email John at Chapalabirders@yahoo.com at least 2 days ahead of time, also indicate whether or not you can bring a car. (We don't always have enough cars).

On Monday March 16, we will meet at 8.00 am to walk the one-mile long Allen Lloyd Trail which has lots of underbrush in which birds love to hide. Expect to see Stripe-headed Sparrow and Groove-billed Ani and hear the Happy Wren - if we are lucky. At about 10.15 we will head to Cafe Negro restaurant for breakfast and complete the bird list.
How to get to the trail head: 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.

On Friday March 27, 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, 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 two days ahead of time; also indicate if you can bring a vehicle, to help in carpool planning. (We don't always have enough cars).
Bird Walk and Trip Reports
On February 5, we had 13 people join us to bird the Lakeshore Road east of Chapala, principally near the Pumping Station. We saw an impressive 74 species including Belted Kingfisher, Black-backed Oriole (endemic), Gadwall, Northern Jacana, Greenish Elaenia, Marsh Wren, American Redstart and both Plumbeous and Warbling Vireos.

On February 17, twenty three people joined us on the Las Palmas Road where we saw 53 species. These included Tricolored Heron, a Black-crowned Night Heron slowy ingesting a large tilapia, Blue Mockingbird, Least Grebe, Lucy's Warbler, Rusty-crowned Ground Sparrow and Orange-billed Nightingale Thrush.

On February 28, we went to the Rosa Amarilla Loop. We had 16 people in four cars (our maximum capacity) and had to turn away four others who wanted to go. We saw Eastern Meadowlark, Crested Caracara, Osprey, Ruddy Duck, Spotted Wren, White-tailed Hawk and Black-necked Stilt out of a total of 53 species.
