Observasjonsdetaljer
Heard clearly near intersection of 4472 & 4475 by both of us. We captured audio via Merlin & played it back to confirm a call match, which we heard. Attempts were made to call the bird so we could secure a sighting. The bird responded to those calls, but we were unable to secure a sighting despite spending well over 20 minutes looking for it. Before posting this audio file, I did listen to a number of Rufous-backed Robin calls as well as Say's Phoebe calls on eBird & Merlin. I know the Say's Phoebe call and find them to be very similar. We both understood Rufous-backed Robin is a Rare bird and we put in the time and effort to locate it for pics, spending well over 20 minutes. Unfortunately, that did not happen. Here is my rationale for Rufous-backed Robin (not Say's Phoebe): 1) When Rufous-backed Robin came up on Merlin, we called it repeatedly and the bird responded, verbally. 2) The Merlin app did not show Say's Phoebe the entire time we spent looking for that bird (well over 20 minutes). We were at the tanks, which did have some water. 3) In my clipped Audacity audio file, at the 7 second mark I hear & see a short burst. I do not hear or see that short burst in the Say's Phoebe audio files that I listened to. However, I do hear & see it in the Rufous-backed Robin audio file (specifically, Merlin's 1st call from Andrew Spencer - 13 second clip @ 2 second mark). 4) eBird Rufous-backed Robin audio file from Anuar Lopez 3/11/23 (36 secs) shows a similar flatter line as did mine, with the left side (beginning of the call) slightly higher than the right side. I also see this in the Isain Contreras audio file from 3/5/23 (56 secs). 5) eBird & Merlin Say's Phoebe audio files show a call that is low on the left (beginning of call), rising quickly for a short period before falling off again as it moves right. Ex. Merlin's 1st call from Jerred Seveyka 19 secs. For that reason and the fact that we are familiar with Say's Phoebe calls out in the field, I did not see a match.
