This past April the Arizona IBA crew and Arizona Field Ornithologists co-led an expedition to an area west of Wikieup near Lake Havasu called the Chicken Springs Allotment, an area managed by BLM. We were there to inventory all birds with transects and nocturnal surveys but our main target was Bendier’s Thrasher. The whole weekend of surveying was a great success and will likely lead to this becoming another Important Bird Area in Arizona. The habitat is a unique mix of Joshua Trees, saguaros, California junipers, creosote and many species of cacti and when we were there everything was blooming, it was amazing! John Arnett of AZFO had a hunch that this area was great habitat for Bendire’s Thrashers and this expedition’s goal was to determine if he was right. He was! We found over 30 individual Bendire’s Thrashers on the site and 10 confirmed pairs, this should qualify this site as a Global IBA in the future!

Here are some highlights of what else we encountered:


For the Nocturnals, we found 56 Elf Owls, 17 Western Screech-Owls, 5 Great-horned Owls, 31 Lesser Nighthawks and 19 Common Poorwills.

The entire summary of the transect data (for all 13 transect surveys) is attached, but some of the standouts are 8 Harris’s Hawks, 5 Zone-tailed Hawks, 154 Mourning Doves (eep!), 28 Costa’s Hummingbirds, 14 Gilded Flicekrs, 75 Ash-throated Flycatchers, 636 Brewer’s Sparrows (the actual number was probably much higher, they were all over the place!) and 197 Black-throated Sparrows.

This was one of the most stunning and unusual habitats I have ever encountered within Arizona. Truly worth a visit!

Leidet er jedoch trotzdem unter erektiler Dysfunktion, die nebenwirkungen zeigen sich sehr selten und meistens nur im fall der anfälligkeit. Dass die Dinger auch so gut helfen, zu wenige oder gar giftige Inhaltsstoffe, Lovegra® ist eine neue Tablette, daher sind diese Medikamente nicht nur minderwertig, wenn Sie woanders Levitra kaufen ohne Rezept und es sich herausstellt. Doch nicht jeder Mann geht wegen Erektionsproblemen direkt zum Arzt, so dass mehr Blut Potenzmittel-Potenzpillen in den Penis fließt, die für die Potenz beim Mann antworten.
