PsittaScene In this Issue: Three Rare Parrots Added To Appendix I of CITES ! Truly stunning displays PPsittasitta By JAMIE GILARDI In mid-October I had the pleasure of visiting Bolivia with a group of avid parrot enthusiasts. My goal was to get some first-hand impressions of two very threatened parrots: the Red-fronted Macaw (Ara rubrogenys) and the Blue-throated Macaw (Ara SceneScene glaucogularis). We have published very little about the Red-fronted Macaw in PsittaScene,a species that is globally Endangered, and lives in the foothills of the Andes in central Bolivia. I had been told that these birds were beautiful in flight, but that Editor didn't prepare me for the truly stunning displays of colour we encountered nearly every time we saw these birds. We spent three days in their mountain home, watching them Rosemary Low, fly through the valleys, drink from the river, and eat from the trees and cornfields. Glanmor House, Hayle, Cornwall, Since we had several very gifted photographers on the trip, I thought it might make a TR27 4HB, UK stronger impression on our readers to present the trip in a collection of photos.

Our intent was to spend the remaining light checking out the blind and the general vicinity, and maybe if we were lucky, to see some birds. Other than a few conures flying over on the way, these birds - a group of more than 20 Red-fronted Macaws - were the first parrots that we saw. It proved to be a highly impressive introduction to the species, as they bounced around on the stiff afternoon breeze, vocalizing and socializing, then gathering and flying off down the valley and out of sight. Below: The Red-fronted Macaw lives only in three major river valleys in central Bolivia, where steep dry canyon walls descend into lush river valleys like the Mizque River valley pictured here. Mark Stafford Right: As part of a continuing series of bird-phones, the town of Santa Cruz has a collection of these beautifully sculpted and painted birds. These included several different species like this toucan, various waterbirds, and a Blue and Gold Macaw. Mark Stafford JDG Bill King JDG Bill King On our second afternoon in the Mizque, we searched the valley looking for the birds and found many of them at one end of the valley. They were mostly perched in a bare tree at the top of a ridge, the strong wind making it easy for them to take flight and soar around on the updrafts in an impressive display of green and orange.

Given that little is known of the species in the wild, there is an urgent need for knowledge of the geographical distribution, population size and threats to its survival. In the northeastern Brazilian state of Bahía, A. a. auricapilla, a subspecies endemic to the state, is distributed along the entire length of the coast. Flocks in the southern range of this subspecies tend to be smaller than those found in the north (south; max. 8 individuals vs. north; max. 30 individuals). This difference may be due to the presence of large coconut (Coco nucifera) plantations that dominate the landscape of the northern coast. Old or dead palms provide ideal nest sites for many bird species. Woodpeckers such as Lineated Woodpecker (Dryocopus lineatus), Campo Flicker (Colaptes campestris), and Green- Barred Woodpecker (C. melanochlorus) excavate nest cavities in the trunks of palms, which when abandoned by these species, are used by Tropical Screech Owl (Otus choliba), Ferrugineous Pygmy Owl (Glaucidium brasilianum), American Kestrel (Falco sparverius),Orange-winged Amazon (Amazona amazonica), and most importantly, threatened Gold-capped birds have been recorded in the reserve, painted on the exterior in either green or Conures. including potential predators of Gold- brown.
