Bulletin #223 - Best of 10 years #4 - Flycatchers and Thrushes

The Tyrannidae family (Tyrant Flycatchers) of the New World is the largest family of birds with some 430 species. Although many are rather plain brown or olive, a few are quite beautiful.

The beautiful Scissor-tailed Flycatcher occurs on grasslands from Kansas to Texas. This male has a pearly gray head and body, salmon underwing and exceptionally long tail feathers. I photographed this bird on the coast during spring migration.

The male Vermilion Flycatcher of the USA southwest is another amazing bird. He has a brown back and wings with red head and underparts and a brown stripe through the eye.

This third flycatcher is the cute little Black Phoebe. It is a resident from west Texas to California. It likes to be near water. I photographed this on a rock by the Pacific in Monterey California. He let me walk right up to him and take his photo.

The Great Crested Flycatcher has been a life long favorite. It is a resident of eastern North America. We had a pair of them nesting in a bird house for many years when I was growing up in Canada. Flycatchers will eat fruit at times and I photographed this one at High Island during spring migration with a bright red mulberry in his mouth. He is typical of the myiarchus genus with brown back, gray breast and yellow belly. I framed a photo of this and put it in my office and some people noticed a whole parade of bugs walking on the underside of the branch. I hadn't seen the bugs!

The thrushes are a worldwide family of 180 species. They are familiar to everyone in North America as the American Robin and bluebirds are thrushes. Many thrushes are beautiful singers.

The Varied Thrush is a bird of the mountains from northern California to Alaska. I have only seen it twice and I was lucky to get this male on the ground in Alaska. It resembles a robin, but has a stripe across the chest and wing bars.


Varied Thrush - male
The Omao is the thrush on the Big Island of Hawaii. As I talked about in bulletins of Hawaii birds, extinctions have been rampant in the Hawaiian Islands. There were 4 thrushes, but 2 have gone extinct in last 30 years and a third one is critically endangered and being raised in captivity to save it. The Omao is the only one that can be seen.

The La Selle Thrush is an endemic to Hispaniola. It also sort of resembles an American Robin with the red breast. One has to go to the Dominican Republic to see this bird. I had one morning to see it, and was successful.

The Bicknell's Thrush is a small thrush that is the hardest to find in North America as it nests on mountain tops in New England and New Brunswick, Canada. I had not made a trip to see it. I was pleasantly surprised when I was in Dominican Republic last November, to discover that 90% of the birds winter there. So I was able to add photos of this species.


Bicknell's Thrush
A cousin of the Bicknell's is the Hermit Thrush. I had seen this bird several times in California, but never in Texas until I found this one in my back yard, one Thanksgiving weekend. He spent the winter in my yard and I photographed him many times. Some mornings I would hear him singing his beautiful song. This was the best of hundreds of photos and was right outside my kitchen window. He had become used to me and I could approach to within 15 feet of him. This photo made it on the Houston Audubon web site as well.

The last is the male Eastern Bluebird. In 25 years of birding in Texas, I have seen it in my yard 4-5 times. This one landed on my bird bath and stayed long enough for me to run and get the camera set up and take his photo. What a treat to have such a beautiful bird by your house.

Bulletin 210 - Dominican Republic #3 - Vireo, Thrushes and Crows

One of the major problems the birds are facing is loss of habitat. Deforestation is a problem everywhere, but in Haiti, it is an ecological disaster.

The contrast between the Dominican Republic and Haiti, which share the same island, is stark. They both have about the same population of 10,000,000, but the Dominican Republic has the highest GDP in the Caribbean or Central America at $93 billion or about $11,000 per person. Haiti is the poorest country in the Americas with a GDP of $12.4 billion and per capita of $1,600. In the Dominican Republic, propane or electricity are used for cooking. However, Haiti still uses wood and charcoal. Because of that, the forests have been decimated. In the 1920s, 60% of Haiti was forested. By 2002, it was less than 2%. The Dominican Republic has set aside large areas for national parks in the mountains and in fact, the forest cover has modestly increased on the last few decades to about 40%.

Almost all the birds I saw on the trip were in the mountains, so Haiti will no longer be available to them as a wintering ground or for the endemic birds. There is no border between the countries, so Haitians are now going into the forests in Dominican Republic and cutting the trees to make charcoal as a cooking fuel. Some areas along the border are being decimated on the Dominican side, even in the national parks. The Dominican government seems powerless to stop it. One of the areas we birded was right along the border and we could hear the people chopping the trees with machetes. They cut the hard wood to make charcoal and use some pines as fuel to dry out the hardwood, so in large areas, one would just see barren hills with a few scattered pines.

Immediately behind me in the picture was dense forest on the Dominican side of the border. Even this photo looks better than it actually is, as this was the rainy season and some grass has sprung up. In the dry season, it is just rock, where once trees and topsoil existed.

Deforestation in Haiti


The Flat-billed Vireo (Vireo nanus) is a Hispaniola endemic bird. It is similar to the White-eyed Vireo on North America, but paler. It has the white spectacles and 2 wing bars. The sexes are similar.

Four species of thrushes were photographed, 1 endemic, 2 Caribbean endemics and 1 wintering from New England. The Hispaniola endemic is the endangered La Selle Thrush (Turdus swalesi). It is found in only 3 small mountainous forest areas on the island. The main problem is habitat loss due to deforestation on Haiti. It is very similar to the American Robin, but has a gray breast and white midline streak on the belly. The sexes are similar. In the mountains where we found it in a National Park, there is a big sign showing the bird and this is the place to observe it. I love the Spanish name 'Zorzal de la Selle'.  We had 2 fly into a fruiting tree directly overhead. The sexes are similar.

And a moment later, another photo.

The second thrush was the same genus. The Red-legged Thrush (Turdus plumbeus) is perhaps the Caribbean counterpart of the American Robin as it is found on lawns, gardens and open areas. It is a resident in the Bahamas, Cuba, Cayman Islands, Hispaniola and Puerto Rico. Then it skips several islands and appears in Dominica. Formerly it was also found on some islands off Honduras. I always find these distributions interesting as why it isn't found between Puerto Rico and Dominica. It skips Virgin Islands, Antigua, St. Kitts, Guadeloupe and Montserrat. Interestingly, the subspecies on Dominica has orange feet and bill rather than red. Maybe it will be split??
I saw the bird on Puerto Rico last year so it wasn't a lifer. It is gray with a red bill and legs.



Red-legged Thrush

The third was the Rufous-throated Solitaire (Myadestes genibarbis). This genus is found only in the New World and Hawaii. In general, myadestes thrushes are slender compared to the plumper turdus genus. This bird is found in Jamaica, Hispaniola, Dominica, Martinique, St. Lucia and St. Vincent, each with their own subspecies. It is grayish with red throat and undertail. The sexes are similar.

The last thrush was another exciting bird to find. It is the Bicknell's Thrush (Catharus bicknelli). This North American bird was a lifer for me. It breeds on mountains in the northeast above 3000 feet elevation. Its range is Vermont, New York, New Hampshire, Maine, southern Quebec, New Brunswick and Nova Scotia. It is essentially identical to the Gray-cheeked Thrush and only was split in 1998. It is best separated by voice, and as usually the birds are silent in migration, most birders have to make the trip to New England in the spring to see this bird. However, 90-95% of the Bicknell's winter on Hispaniola and they do sing, so I was able to find and photo the bird. It is a small brown thrush with spotted breast and no eye-ring.

Crows, jays and magpies make up the corvidae family. These were another interesting geographical distribution for me. There are 5 endemic species of crow in the Caribbean, but no jays. Why do some birds in a family, but not others occur? Both crows and jays are in Florida, and it is less than 100 miles to Cuba and the Bahamas, but the crows made it and the jays didn't or at least never survived and populated the islands. The 5 species of crow are just on the largest islands, 2 each on Cuba and Hispaniola and 1 on Jamaica.

The Hispaniolan Palm Crow (Corvus palmarum) is a smallish (17") all black crow closely related to the Fish Crow in Florida. We saw a flock of about 20. He is nothing special to look at, but he was a lifer.

The other is the White-necked Crow (Corvus leucognaphalus). He is larger (20") and found in large flocks,  despite being listed as threatened. The white feathers on the nape of the neck are only seen during display. However, unusal for a crow, he has a bright red eye.
