All the four perceiver obtained really specimens, specifically those out-of close by the fresh crossbreed region

Morphological evaluations

I scored mature specimen skins was able on the STRIBC (Letter =67), new American Art gallery from Sheer Records (AMNH, N =25), together with You Federal Art gallery bird range (USNM, Letter = 10) out of Costa Rica, Panama, and you can Colombia for each and every off three phenotypic characteristics: i) dorsal plumage, ii) ventral plumage, and iii) face shield ornamentation. After asiatisk brudebyrГҐ the , MJM, Sel-, or over to 3 most other perceiver (see Extra document step one: Desk S1) scored for every bird individually to the a measure of 0 – 1, in which 0 illustrated an excellent phenotypically absolute Jacana spinosa, and you may 1 portrayed a beneficial phenotypically sheer Jacana jacana (centered on evaluations that have skins away from outside the contact zone), and in addition we averaged the fresh score each feature since phenotypic hybrid index for every sample . Specimens with phenotypic crossbreed indicator lower than 0.ten were classified as the "pure" spinosa, if you're an inventory off 0.90 or more is scored just like the "pure" jacana. A get anywhere between 0.10 and 0.twenty five is actually categorized as the "spinosa-like", whereas an inventory anywhere between 0.75 and you can 0.90 is actually classified because "jacana-like".
