pardal-de-java

Um dos pássaros de gaiola mais populares no Leste Asiático, os pardais-de-java são tentilhões vistosos com plumagem cinza, cabeça preta marcante, manchas brancas características nas bochechas e bico vermelho brilhante. Nativos de Java e Bali, na Indonésia, foram introduzidos em muitas partes da Ásia, África e Américas. Habitam pastagens abertas, arrozais e terras agrícolas, frequentemente tornando-se pragas para as lavouras de arroz. Classificados como Vulneráveis em sua área de distribuição nativa devido à intensa pressão de captura para o comércio de pássaros em gaiola.
