White-throated Flycatcher in Amador, a report by Venicio Wilson

On September 5, while birding with Diego Postigo and his 6 year old son Carlos, I saw an Empidonax with relatively long bill, whitish lores, pale yellow belly and a totally white throat and upper chest.
Bird was moving constanly. Did not heard it call. I send this pictures to Ito (Genover) Santamaria and he agrees that the bird is a White-throated Flycatcher. The bird was spoted near the 2nd balcony on the walkway from the Yacht Club to Biomuseo.

Streaked Xenops at Río Mono, a report by Bill Adsett

As a follow-up to Darién's "Xenornis" report of Streaked Xenops possibly nesting at the río Mono bridge in February, we had good looks at one at the same place on August 19. Despite difficult light, we got some photos that show well the colour and streaking on the lower parts, but not so well those on the upper parts. However, it appears that the streaking on the upper parts is pretty much confined to the neck and shoulders, and does not continue down the upper back as in some races. Dave might be able to elaborate more on that.
Are we assuming that these birds are the incomptus race described by Wetmore from Cerro Pirre? I cannot find an illustration of that race anywhere, but the description fits pretty well. In Restall's Birds of Northern South America there is an illustrtion of hetererus of eastern Colombia which is quite similar to the Bayano bird.
[And elaborate he did. Dave Klauber:
Thanks for the photos Bill. The streaking on the back goes from the crown through only the upper mantle, which is consistent with the illustration in Handbook of the Birds of The World, although they illustrate a different race, as well as Birds of Ecuador (the Columbian guide has no picture). They also list incomptus as strictly Cerro Pirre. But this seems more ikely than the septentrionalis race of Costa Rica and western Panama. Hey, maybe a new race- ha!
They say that geographical variation is slight and subspecies are based on just a few old specimens. I quote "eleven subspecies very tentatively recognized".]

I also enclose two photos of one of 4 Wing-banded Antbirds found at the San Francisco Reserve, Tortí on August 18.

Whistling Herons still in Malibú, a report by Bill and Claudia Ahrens

On our way back to the city on August 26 we stopped to scan the ponds at the Malibu development in Nueva Gorgona with Cindy Lieurance and Leslie Lieurance.

The pond seen from the fence had about 30 Least Grebes and we found 1 Pied-billed Grebe. The pond at the back of the development is in a much more natural state and had a number of other species. Most notable - there was a Capped Heron on the far shore and a non-breeding adult Black Tern. We also saw a single American Kestrel and 2 Whistling Heron in the field area.
Leslie Lieurance shared this video of the sighting.

Least Bitterns at the Gamboa Ammo Dump, a report by Cedric Kinschots

Joris Deruwe and I found at least 2 Least Bitterns at Ammo Dump on Sunday, August 23. The birds were constantly flying back and forth between the shoreline and the tall vegetation on the floating island. On Sunday, the wind had blown the island to the northeast corner of the pond, near the Ammo depot entrance gate, so it was pretty far away. Quality is not optimal due to the distance, but I would say this is the resident race.

Bare-necked Umbrellabird en El Copé, un reporte por Rolando Jordán

El sábado 22 de agosto encontramos tres ejemplares de Bare-necked Umbrellabird [incluyedo este macho adulto] mientras pajareábamos en El Copé. Los pájaros respondieron al play back en pocos minutos. Inicialmente los observamos a escasos metros del inicio del sendero de la Rana Dorada como a las 7:30am, un par de horas más tarde los vimos nuevamente en el mismo sendero y a las 3:00 pm los volvimos a encontrar en la salida. Además vimos Dull-mantled Antbird, Orange-bellied Trogon, Yellow-eared Toucanet, Russet Antshrike, Northern Schiffornis y 30 especies más. El guía fue Ariel Aguirre y nos acompañaron Glen y Janet Lee, y Craig Bennet.

Umbrellabirds in El Copé, a report by Cedric Kinschots

I decided to follow up on your Umbrellabird sighting and visited El Copé this morning. At the exact spot mentioned in your report (the intersections of the Cuerpo de Paz and Auxiliary Trails with the Las Ranas trail, I played the tape and immediately not one, not two but three Umbrellabirds flew in.
Some pictures attached, they appear to be one adult and two younger males. Other good birds this morning were Crested Guan and Snowcap

I also saw several Smoky-brown Woodpeckers. I have been seeing these woodpeckers in El Copé for 12 years, even though Coclé is not mentioned in the range description of that species in Angehr nor Ridgley I believe.

Fledgeling Spot-crowned Barbets at Achiote, a report by Bill Adsett

Mariló Castro had been monitoring daily for months an active Spot-crowned Barbet nest in a hole in a dead trunk behind CEASPA's El Tucán Community Center at Achiote, Colón. On June 9 she and I (visiting for the day) were alarmed to find that the nest had been ripped open all the way down one side during the night or extremely early in the morning, and the adult and young birds were nowhere to be found. It was feared a predator had taken them. But then a barbet was heard vocalising nearby and we were relieved to find both parents and two fledglings safe and sound in a fruiting tree. One fledgling was in male plumage, the other in female plumage (is this unusual?). The male parent was feeding the female fledgling (and vocalising) and the female parent was feeding the male fledgling. Despite having left the nest for the first time only a few hours previously, both young birds were jumping from branch to branch and flying strongly and proficiently.

The young male had been seen before peering out of the nest waiting to be fed, but this was the first time the young female bird had been seen. The adult female and young male have not been seen since, but the adult male and young female continue to feed around the Center, especially in the early morning.

Hopefully they will remain there for several days to come. The only questions are: where are they roosting now that the nest has been destroyed, where are the adult female and young male (hopefully not far away), and where are they all roosting?
