Description of intermediate phenotypes between Passer hispaniolensis and Passer domesticus

Abstract

[EN] 23 intermediate phenotypes between Passer hispaniolensis and P. domesticus collected in Spain are described. Their hybrid index score, which is based on color pattern, is correlated with some body measurements, in which they are intermediate between both pure phenotypes

El tamaño de sus picos y tarsos es intermedio entre los de las dos especies citadas, existiendo una correlación positiva entre dichas medidas y el índice de hibridación basado en los caracteres del plumaje que diferencian a ambas especies.
