Shrike-tyrant - help from ANP Península Valdés - Punta Delgada, Argentina (1 Viewer)

We took this photo at a rest stop in this protected natural area. Another birder photographing the same bird said he thought it was a Black-billed Shrike-tyrant. After looking at photos of similar birds it looks more like a Lesser Shrike-tyrant though the bill seems a bit too large for a Lesser. Possibly, a Gray-bellied Shrike-tyrant.? Thoughts? Thanks!

Looking at the range maps in my ancient field guide, it looks like Grey-bellied and Lesser are the only ones in range. Bill shape looks a better fit for Grey-bellied to me. I haven't seen either for more than 20 years now, so get another opinion :)

Thank you, Larry. Right, the Black-billed is listed as a rare species on eBird for this area. I agree. The bill looks more likely that of Gray-bellied. We'll see if anyone chimes in. Thanks again!

Probably doesn't mean much, but looking at my notebook from 20 years ago, the only Shrike-Tyrant I noticed on the peninsular was Grey-bellied.
