I was greeted by a close group of about twenty or thirty Swallow-tailed Kites, circling on thermals on Cerro Azul, where these photos were taken on my first morning in Panama. Possibly migrating, though there is a resident population.

Common Potoo

Photos copyright: TC/monacoeye • Do not copy • Valle de Anton • 3 May 2010
Bird name: Common Potoo
Latin: Nyctibius griseus
Other: Grey Potoo, Lesser Potoo • Urutaú menor (Es) • Urutau-comum (Br)
Family: Nyctibiidae
Range: Costa Rica to Argentina
A chip off the old block - a Common Potoo and chick doing a very convincing impression of a piece of wood. The adult will have a laid a single egg, which has now hatched, in a depression in the top of this stump.
When Common Potoos hear a potential predator approach they adopt this freeze position, very slowly, which serves as even better camouflage than their usual pose.
Potoos are in the Caprimulgiformes order with the Nightjars and Frogmouths, but have their own family the Nyctibiidae with a single genus with seven species, which all live in tropical Central and South America. They hunt insects from a perch at night.

Family: Nyctibiidae

This Great Potoo was seen in the Soberania National Park in central Panama, high on a limb near the main road. The species is found in most of tropical Central and South America from Guatemala to southeastern Brazil.
At 50-60 cm, the Great Potoo is the largest of the seven Potoos, and the largest bird in its order. It is nocturnal, preying on large flying insects and sometimes bats. It’s very well camouflaged during the day and difficult to spot.
Slightly reminiscent of Lewis Caroll’s Cheshire Cat.

King Vulture

Photo copyright: monacoeye • Do not copy • Iguaçu 2006 - Panama 25 April 2010
Bird name: King Vulture
Latin: Sarcoramphus papa
Other: Urubu-rei (Br) • Zamuro rey (Es)
Family: Cathartidae • Vultures
The King Vulture is the only vulture with a thick black rear wing band - the rest is white. And he has a distinctive colourful head. The range of the King Vulture extends through much of South and Central America, up to the Yucatan peninsula.

Common Nighthawk

Photo copyright: monacoeye • Do not copy • West of Panama Canal • 30 April 2010
Bird name: Common Nighthawk
Latin: Chordeiles minor
Other: Atajacaminos común (Es), Añapero yanqui (!) o boreal • Bacurau-norte-americano (Br) • Bullbat
Family: Caprimulgidae • Nightjars
The Common Nighthawk breeds in North America and spends the northern winter in South and Central America.
This male (male has white throat and tailband, female brown) was seen about 100 km west of the Panama Canal at the end of April.
The Common Nighthawk can be differentiated in photos from the Lesser Nighthawk only with difficulty, especially when it is lying on a branch.
The telltale clues are the staggered white wingbar (usually squarer in the Lesser Nighthawk) which is also said to be proportionally higher up the wing in the Common. The Common Nighthawk also lacks the buff spots of the Lesser above the white wingbar on the primaries. And the general colouring is more contrasty than the Lesser. The Common Nighthawk is larger than the Lesser Nighthawk, despite the Latin minor species name.
Common Nighthawks lay their eggs on bare ground and hunt for insects on the wing at dusk or night. They can be seen lying on horizontal branches during the day.More photos...
Lesser Nighthawk

Photo copyright: monacoeye • Do not copy • Summit Gardens • 27 April 2010
Bird name: Lesser Nighthawk
Latin: Chordeiles acutipennis
Other: Atajacaminos (Es), Chotacabras • Bacurau-de-asa-fina (Br)
Family: Caprimulgidae • Nightjars
The Lesser Nighthawk is found from the southwestern United States all the way to Brazil. This individual was seen east of the Panama Canal in Summit Gardens, at the end of April.
The Lesser Nighthawk can be differentiated in photos from the Common Nighthawk by the staggered white wingbar in the Common, which is usually squarer in the Lesser Nightjar, and which is also said to be proportionally higher up the wing in the Common. The Common Nighthawk also lacks the buff spots of the Lesser Nighthawk above the white wingbar on the primaries. The general colouring of the Common is more contrasty than the Lesser. The Lesser Nighthawk is smaller than the Common Nighthawk, with a less deeply forked tail.
Lesser Nighthawks usually nest on bare ground and hunt for flying insects at dusk or night. They often spend their days sitting on branches.
Rufous Nightjar

Photo copyright: monacoeye • Do not copy • Pipeline Road, Panama • 24 April 2010
Bird name: Rufous Nightjar
Latin: Caprimulgus rufus
Other: João-corta-pão (Br)
Family: Caprimulgidae • Nightjars
The Rufous Nightjar is found from Costa Rica to Argentina.
This individual was sitting on a chick (not really visible here) in its “nest” on the ground, near Pipeline Road, east of the Panama Canal at the end of April. I think the chick might be the second patch of white on the chest.
It was very well camouflaged on the canopy floor of fallen leaves, and characteristically very difficult to spot even when looking straight at it.

I’ve removed the “Passeriformes” tag from entries, and its corresponding page. The latter had hundreds of entries so was slow to load and it was difficult to find a particular bird on it. Until Google deindexes the page, if you’ve arrived from Google and not found the bird you are looking for, please search the Alphabetical index linked on the left (updated every month or so), or look in the families of birds further down on the left of the page, which are always up-to-date. Thanks!
