Nestled within the lush forests of Nepal resides a rare and strikingly beautiful bird – the Purple Cochoa (Cochoa purpurea). This enigmatic avian species has captivated birdwatchers and nature enthusiasts alike with its fascinating taxonomy, physical features, habitat preferences, and diet. In this article, we will embark on a journey to learn about the Purple Cochoa's presence in Nepal and uncover an interesting aspect of this remarkable bird.
Taxonomy: Classifying the Purple Cochoa
The Purple Cochoa belongs to the family Turdidae – a diverse group of birds commonly referred to as true thrushes. Within this family, the Cochoa genus is home to only four species, two of which are found in Nepal. The scientific name for this elusive creature is 'Cochoa purpurea,' representing the distinct purple coloration that sets it apart from its relatives.
Physical Features: A Glimpse at Nature's Artistry
As its name suggests, the Purple Cochoa is predominantly purple, although it displays a fascinating array of colors throughout its plumage. Male birds exhibit a mix of iridescent purple along their back and tail feathers, while their head, throat, and upper breast display hues of velvety blue. In contrast, female Purple Cochoas are characterized by olive-green upperparts and a yellowish-orange tinge on their underparts. Both sexes are adorned with white bars across their wings—a feature that allows for easy identification.
Habitat: Home Amongst Lush Canopies
Purple Cochoas are native to South Asia and can be found in countries like Nepal, Bhutan, India, Myanmar, and China. Preferring moist and dense broadleaf forests that are rich in undergrowth, these birds thrive in areas with altitudes ranging from 1500 to 3300 meters. In Nepal, they are largely concentrated in protected areas such as Annapurna Conservation Area, Sagarmatha National Park, Langtang National Park, and Makalu Barun National Park.
Diet: Foraging the Forest Floors
The dietary preferences of Purple Cochoas are predominantly insectivorous, with a particular fondness for beetles, snails, and caterpillars. They can often be seen foraging methodically through the forest floor and perusing tree barks for their next meal. Seasonally, they also consume small fruits and berries that supplement their diet.
Presence in Nepal: Unmasking a Hidden Treasure
Although their population is not extensively researched, Purple Cochoas are believed to be rare or local resident breeders in Nepal, with some records of seasonal altitudinal movement. The presence of these enigmatic birds is a testament to the rich biodiversity found within Nepal's dense forests and protected areas.
Interesting Point: Singing a Secret Serenade
Purple Cochoas possess an intriguing vocalization characterized by an infrequent metallic-like whistle heard intermittently throughout the day. These secretive songs typically emerge from thickets and dense foliage – an auditory gem that remains concealed from its admirers.
In conclusion, the Purple Cochoa remains one of Nepal's lesser-known avian treasures. With increased awareness about its taxonomy, physical features, habitat preferences, diet, and other fascinating aspects like its secretive vocalizations—our appreciation for this elusive species will only intensify. As we continue to learn more about the Purple Cochoa (Cochoa purpurea), it serves as a symbol of Nepal's rich natural heritage and blends harmoniously into the nation's remarkable avifauna
