There are 400-450 species of birds in Taiwan that include those migrating from northern Asia either arriving in Taiwan for the winter or stopping over, on their way to, e.g., Indonesia.
There was a time when the sky above Danshui River was teeming with eagles hunting for fish [four of the most numerous: Chinese goshawk, gray-faced buzzard eagle, Formosan crested goshawk, and serpent eagle]. Now, with their winter nesting sites crowded out by humans in 觀音山 area, you are lucky to spot one or two on a good day.
In the wetlands and forests, however, a few other species have apparently survived and done well:
[Above and below: 鷺鷥white Egret, commonly sighted in riversides and rice paddies, strolling in lady-like grace; there are 6 species of egrets in Taiwan]
[Above: a 藍磯鶇 Blue Rock-thrush and below: a very rare migratory 藍尾鴝Red-flanked Bluetail known as "rooftop violinist" for its trilling songs]
[Below: a 樹鵲 Himalayan Tree Pie - usually seen in groups, large and loud residents of parks in Taipei]
[Above: a 爪哇八哥White-vented Myna, this one in a bamboo bush in Danshui; and below: a 五色鳥Muller's Barbet, a loner with feathers of 5 different colors]
[Above: a 翠鳥Kingfisher, aka a flying jewel; and below: a 黃尾鴝Daurian Redstart, another visitor from the north]The good news is, with planned conservation in Danshui, Guan-du and Taipei, these beautiful birds seem to be making a comeback. We hope the magnificent eagles of 觀音山, all 10 species of them do as well.
