Oriental Cuckoo

Cuculus optatus

The Oriental cuckoo or Horsfields cuckoo (Cuculus optatus) is a bird belonging to the genus Cuculus in the cuckoo family Cuculidae. It was formerly classified as a subspecies of the Himalayan cuckoo (C. saturatus), with the name 'Oriental cuckoo' used for the combined species. Differences in voice and size suggest that it should be treated as a separate species. The binomial name Cuculus horsfieldi has often been used instead of Cuculus optatus, but is now usually considered to be a junior synonym.

Simply fantastic
I love this app, it puts so much fun into recording the birds I’ve seen and heard while I’m out and about. The interface is user-friendly and suitable for all ages. It’s great to collect badges and to review my “lists”.

I really like Birda. I also use other birding apps and have Birda with E-bird going at the same time.

Easy to use and accurate
Love this app. It is easy to use and accurate, Their backup communication is really good. I noted a missing species. All through the process, I was kept informed about the progress in correcting the information. I now have the corrected, updated version. 😁 Thanks!

Terrific App for Birders
Downloaded Birda around the time my interest in birding was sparked, and it has been a terrific app to help me (1) share my experience, (2) document my sightings, and (3) learn more about birds in general. That said, I also believe Birda is a fantastic app for birders of all experience levels. Great community!
