29 December. Azapa Valley & Arica.
Arid deserts rise from the outskirts of Arica, totally devoid of vegetation, a world of sand and rock rising into mountains and stretching for hundreds of kilometres north to south. Cutting through this, two thin slivers of greenery, the Lutra Valley to the north and the Azapa a little further south. Both cutting deep through the deserts, these not only serve as routeways between the coast and high Andes, but also are excellent birding locations, the southern outposts of a whole range of essentially Peruvian species.
No car this day, so took a collective taxi to San Miguel de Azapa, just15 km from Arica. Plan was to visit the gardens of the Museo Arqueológico, then later another site just beyond the town, both hotspots for hummingbirds. We arrived too early for the museum however, so started off by exploring scrub and orchards in the surrounding area – plenty of new birds here, amongst them Croaking Ground-Doves and their weird calls, Cinereous Conebills, Chestnut-throated Seedeaters and Blue-black Grassquits. Also a dozen or so Vermilion Flycatchers, numerous West Peruvian Doves, Peruvian White-crested Elaenia and masses and masses of Turkey Vultures rising from the dune slopes. By 10 a.m. it was already stinking hot – fortunately the doors of the museum were now opening, allowing us access to their shaded garden, a small oasis of watered lawns, towering palms and, critically, an abundance of flowering shrubs. With mummies, skulls and bones beckoning, my younger companion would have been quite happy to head straight into the museum itself, but was patient enough to allow me to linger for a half hour and more at one particularly productive line of shrubs. Hummingbirds zipping in and out with much regularity, Oasis Hummingbird common, the tiny Peruvian Sheartail even more so. A number of years ago, this latter hummingbird was unknown in Chile, but has since colonised the northern valleys and is today probably the most common species present. Unfortunately, pretty much simultaneously a third hummingbird, the Chilean Woodstar, has undergone a massive decline, disappearing from its localities in southern Peru and retreating at an alarming rate in its few Chilean localities.
Sitting here in the museum gardens, the challenge was of course to find a Chilean Woodstar. Adult males are easy enough, but the females and immatures are very similar to female Peruvian Sheartails. And typically, most of the hummingbirds present were indeed females and immatures! Zipping around at speed, many seeming to show a varying degree in underside shade and throat coloration, none seemed to tick the boxes for Chilean Woodstar. Did get a frustrating glimpse though of what appeared to be a male sporting full tail – was perched briefly at the far side of a bush, then zipped away, never to return.
Heat building, took a little break to satisfy the ghoulish desires of the little one to peer at the Chinchorro mummies. With exhibits depicting the early culture of the Chinchorro people, the small collection of mummified bodies and heads did their job, the little one leaving some time later quite content.
Thereafter, the next destination was at a 'hummingbird garden' a couple of kilometres further up the Azapa Valley. This was a smashing site, a dedicated lady turning her relative small plot into a mosaic of shrubs and trees all designed to provide cover and feeding for hummingbirds and others. Winding through the shrubs and an eclectic mix of odd ornaments, armchairs and small gazebos, small paths take you on a journey around the garden. Oasis Hummingbird and Peruvian Sheartail are both abundant, hovering at flowers and in general pursuit of each other, but so is the garden good for other species – more Croaking Ground-Doves, my first Slender-billed Finches, four Hooded Siskins and, in an orchard just beyond the fence, four Groove-billed Ani. After considerable effort with the hummingbirds, I found what I though was a female Chilean Woodstar ...but I am still somewhat doubtful over the identification, maybe just another Peruvian Sheartail.
A pair of Harris Hawks send panic amongst chickens as they tried to grab a free- ranger, two unknown parakeets flew over. Early afternoon, the heat was now really up! Walked back to the museum for another attempt to relocate the presumed male Chilean Woodstar from earlier in the day. Far less activity in the afternoon, but luck was in – after about 20 minutes, perching in exactly the same spot as had been in the morning, the male Chilean Woodstar did indeed appear, tail perhaps not fully grown, but crossing in its distinctive form when perched. And then, as earlier, off it zipped again, briefly pursued by a second hummingbird, both vanishing beyond the museum grounds.
Walked up to the main road and caught a collective taxi back to Arica. Spent the evening on a beach just north of the town – Peruvian Boobies, Band-tailed Gulls, Grey Gulls, Elegant Terns, Blackish Oystercatchers, just some of the birds present. To the north, vast clouds of gulls and terns roosted on distant beaches ...would check them out in coming days. As dusk approached, I made my way back to the airport and picked up a rental car, next morning would see us venturing into the mountains.
