Proposal (933) to South American Classification Committee

 

 

Add Tyrannus forficatus (Scissor-tailed Flycatcher) to main list

 

Effect on South American CL: This transfers a species from the Hypothetical List to the main list as a Vagrant species.

 

Background: Tyrannus forficatus is a regular migrant to the north of Costa Rica, and less common to the south of Panama (Fig. 1; eBird 2022).

New records with evidence: One individual photographed in Chocó (Colombia) on 20 December 2018 by Rob Felix (https://ebird.org/checklist/S51126799).

 

Recommendation: The identification is obvious, and the photograph is archived, so I recommend a YES on this.

Comments from Remsen: “YES. Obviously meets all qualifications for addition to main list.”

 

Comments from Robbins: “YES for adding it to the list. Photos leave no doubt.”

 

Comments from Stiles: “Definitely YES - the photo clinches it.”

 

Comments from Areta: “YES”

 

Comments from Lane: “YES. The photos in this eBird list clearly show T. forficatus, and it looks like an overshooting migrant to Chocó should be expected.”

 

Comments from Bonaccorso: “YES, absolutely agree.”

 

Comments from Claramunt: “YES.”

 

Comments from Zimmer:  “YES.  The two photos in the linked eBird list from the Chocó region of Colombia, are, without question, of a Scissor-tailed Flycatcher.  I used to see this species in small numbers on the Pacific Slope of Costa Rica (south to at least the Carara/Tarcoles region) on virtually every March-April trip, so not a big surprise that the occasional overshoot might make it as far south as the Chocó.”

 

Comments from Pacheco:  “YES.”
