Fish of Thailand

The birds of Thailand number nearly one thousand species, of which approximately 45 are rare or accidental. At least seven bird species previously found in Thailand have since been made locally extinct, and approximately fifty of Thailand's bird species are globally threatened. ^[2]

In 1991, it was estimated that 159 resident and 23 migratory species were endangered or vulnerable due to forest clearance, illegal logging, hunting and habitat degradation, especially in the lowlands. The species most affected are large water birds whose wetland habitat has been largely lost to agriculture, and forest species, as deforestation for agriculture and logging have removed and degraded portions of the woodlands. ^[3]
