2022 BioBlitz Observation Summary

The 2022 BioBlitz was a great success, even with heatwave in which a high of 108F was recorded.

Based on the sign-in sheet, the following observers participated: @amzapp, @annikaml, @bacchusrock, @centratex, @currenfrasch, @gcwarbler, @jcochran706, @k8thegr8, @kimberlietx, @knightericm, @mikef451, @lizziedub, @nanofishology, @pbynum, @pfau_tarleton, @rlhardin , @rymcdaniel, @sambiology, @tadamcochran, @textileranger.


  1. Let me know via iNat email whose properties you visited including any comment you would like me to share with a particular owner. I intend to send a personalized email to each owner that granted us access. Last names instead of Phase/Tract is easier. If you only stayed around the hangar, let me know that as well.
  2. Post a comment here once you have finished uploading your observations from the event. We will run some stats once everyone has posted.

New additions:
Three new birds: chuck=will's-widow, olive sparrow, and curve-billed thrasher.
Plants / insects: we need to wait for stats.

This journal post is the comprehensive list of birds observed at the ranch, those observed during the BioBlitz, and links to the eBird checklists. Someone recorded a rufous hummingbird but that would be very rare. I need some supporting evidence, even if it is just a comment before I can submit it in eBird.

Scott's Oriole

This is an interesting article about the Scott's Oriole's nesting at the ranch. They reused their nest for a number of years, which is unusual.

Navigation Logistics for 2022 ICR BioBlitz

Here are some resources for getting to the ranch for the 2022 BioBlitz and for getting around once there.

  1. Driving directions from Rocksprings to the hangar with pictures. We will also have some signs out showing the way.
  2. Same driving directions as in 1 but without pictures in case you want to print a short version.
  3. Guidance for figuring out where you are when on the ranch.
  4. Map of the ranch indicating for which tracts we have permission to wander.
  5. Map of the ranch indicating how rough the roads are. Green = good for all vehicles; Orange = quite rough or steep; Yellow = in between.
