Our 2023 Arizona Second Spring was characterized by overall dry conditions with the notable exception of a magnificent thunderstorm that rolled through Tucson and environs on the first afternoon and evening of the tour. Indeed, it would have flooded us out of our planned visit to Box Canyon had we not had the van issue to resolve. After that, it was pretty smooth sailing weather-wise.

We started off in Tucson and then made our way eastward to the Chiricahuas for three nights, two nights in Sierra Vista, and then on to Nogales and environs. It was a good trip for rarities, a not-so-good trip for owls (likely due to an ongoing drought), but an exceptional trip for hummingbirds! Aside from Allen’s (possible), Ruby-throated (fewer than 10 records for the state), Cinnamon (one record for the state), and Bumblebee (one record of two from the 1890s), we saw all of the species that have ever been recorded in the state! I think this was a first for a Field Guides Arizona Tour.

There were many highlights along the way and when polled at the end of the tour, some favorites emerged. Top the list of favorites was the Five-striped Sparrow, an impressive, range-restricted species that took us some effort to track down. Then it was a five way tie for the second place spot, with Plain-capped Starthroat, Berylline Hummingbird, Whiskered Screech-Owl, Montezuma Quail, and Rufous-capped Warbler all getting two votes. Filling out the survey were Elegant Trogon, Violet-crowned Hummingbird, Wilson’s Phalarope, Sulphur-bellied Flycatcher, Rose-throated Becard, and Varied Bunting. Of course there were some wonderful mammals seen, including a seldom seen Kit Fox, and a variety of herps including two species of rattlesnake. We even managed to see a few of Arizona’s diverse scorpion fauna under black light.

More than anything else, there was some terrific camaraderie on this tour which I am grateful for. Lots of terrific spotting, Bill’s fabulous photography, and lots of good story telling. Thank you all for making the trip such a success. I look forward to seeing all of you again and wish you the best in birding.

A really good showing of this species in Ash Canyon where we figured that we saw four in total!

Field Guides Birding Tours

BLACK-CHINNED HUMMINGBIRD (Archilochus alexandri)

COSTA'S HUMMINGBIRD (Calypte costae)

It was a good showing for this species with sightings at three locations beginning with one in Green Valley.

It was a tremendous tour for this species. Normally one or two might be seen, but we had them at six different sites.

RUFOUS HUMMINGBIRD (Selasphorus rufus)

BROAD-TAILED HUMMINGBIRD (Selasphorus platycercus)

BROAD-BILLED HUMMINGBIRD (Cynanthus latirostris)

VIOLET-CROWNED HUMMINGBIRD (Leucolia violiceps)

This was another species that seemed to be exceptionally numerous this year. We had sightings at five different locations.

Field Guides Birding Tours
This lovely Red-faced Warbler was a treat from our first afternoon on Mt. Lemmon as captured by Bill Thompson.

BERYLLINE HUMMINGBIRD (Saucerottia beryllina)

HARRIS'S HAWK (Parabuteo unicinctus)

Another scarce species on our tour route, we had a breeding family group in northeast Tucson on the first full day of the trip.

Field Guides Birding Tours
Another highly desired species is the Lucifer Hummingbird, and we managed to see up to four at the Ash Canyon Bird Sanctuary, like this one photographed by Chris Benesh.

SCOTT'S ORIOLE (Icterus parisorum)

Named after Old Fuss And Feathers, Winfield Scott, a general in the US Army. As a result of his involvement with the forced relocation of thousands of Native Americans where many died along the journey, the oriole named in his honor has been at the top of the list of species to be re-named in the future.

RED-WINGED BLACKBIRD (Agelaius phoeniceus)

BRONZED COWBIRD (Molothrus aeneus)

BROWN-HEADED COWBIRD (Molothrus ater)

Always a crowd-pleaser! We were fortunate to see it well at Rose Canyon Lake and again in Pinery Canyon.

PAINTED REDSTART (Myioborus pictus)

Another striking species that is a wonderful part of the Madrean oak pine forests of Arizona.
