Thursday, April 12
Start and end time:
6:00 am – noon
Provided box breakfast
We’ll be exploring a seven mile stretch of the San Pedro River owned by BHP which has been maintained by them in near pristine condition and represents the nearest example we have of what this river system might have looked like pre-Columbus. With a large cottonwood gallery and wide flanking mesquite bosque and Sonoran highlands, it contains a wide diversity of Southwestern species and in startling high density. Normally barred to public access, this trip will provide a special look at an area intended to form the nexus of a proposed National Wildlife Refuge.
Walking the areas flanking the river, we will be looking for a host of Southwestern riparian and mesquite inhabitants including multiple members of the Myiarchus and Tyrannus flycatchers, several raptors that nest here including Zone-tailed Hawk and Common Blackhawk, Lucy’s Warbler, and Rufous-winged Sparrow. Of particular interest will be the high breeding densities of several species including Northern Beardless-Tyrannulet, Bell’s Vireo, Summer Tanager, and Yellow-breasted Chat.
Recommended Gear and Cautions:
Intermediate level. It will be hot later in the morning, so a wide-brimmed hat with cooler clothing is advised but with long pants and sleeves as there are no established trails and the thornbrush can be vexing. Water bottles are also a must.
