After more than three weeks of travelling we’ve reached the most westerly point on our Tex-Az birding trip itinerary. Green Valley is a convenient location for accessing the western canyons of Madera, Montosa and Box. Our day started at Paton – nothing new but some nice early morning birding anyway. We then drove through the outskirts of the border town of Nogales to reach a stretch of the Juan Bautista De Anza trail which, in the past, has provided some special birds – but not on this occasion. It wasn’t until Amado water treatment plant that we added our first tick of the day – a lone Ring-billed Duck, amidst the flock of Black-bellied whistlers. After a brief recce of Montosa Canyon – a new location for us, we had lunch and checked in at the Comfort Inn, our base for the next couple of nights. We then headed out to Madera Canyon for an afternoon and evening birding session. One of our target birds was Berylline Hummingbird, which had been reported from Madera Kubo B&B. We arrived just as the bird was spotted visiting the feeders. It obligingly hung about for us to obtain photos. A US tick for us. We also added Yellow-eyed Junco as a trip tick. We did a bit more general birding – killing time before dusk. At the top carpark we heard Whiskered Screech Owl calling and saw our first Lesser Nighthawk emerging. Later, at the Amphitheatre, we added Western Screech Owl and Northern Pygmy Owl. Our total for the trip is now around 340 – just ten more species to reach our ambitious trip target.
