Black Saw-wing

Psalidoprocne pristoptera

The black saw-wing (Psalidoprocne pristoptera), also known as the blue saw-wing or black rough-winged swallow, is a small passerine bird in the swallow family. The black rough-winged swallow is a small swallow at 13–15 cm length with a forked tail. Its plumage is blue-glossed black. Sexes are similar, but the female has shorter outer tail feathers, and less obvious wing serrations. Juveniles are brown with little gloss, and have short tails. There are many subspecies of this swallow, which some authorities may split into different species. In particular, four northeastern races, including nominate P. p. pristoptera, have conspicuous white underwing coverts (all other subspecies are green-glossed and have completely dark underwings), and may be split as the eastern rough-winged swallow or eastern saw-wing (swallow), P. orientalis. This leaves P. p. holomelaena as the black rough-winged swallow, P. holomelaena. Other subspecies are also sometimes elevated to species status, but Turner and Rose take the view that all the races of the black rough-winged swallow are, at best, incipient species.

Loving it
I really enjoy being able to interact with other birders on this platform! This seems like a great way to meet other birders and find some new spots.

Really great app
It’s easy to use and it’s fun to log the birds you notice on a walk or just in your garden. There’s a option to record the birds you see in a session which is really nice. Good excuse to stop for a while and just watch birds. I am also enjoying the information part where you can find out fact about birds from all over the world.

Fun way to add to your birdwatching experience
I enjoy watching birds in my backyard, but this app helped me really pay attention while on vacation this summer. It was fun to add new birds to my bird watching app.

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 β€œlists”.

Great app for beginner twitchers
I’ve had a passion of photographing birds for a long time now but have only just gotten into proper birdwatching, and this app is brilliant for those just getting started. There is a great sense of community among users and the app is very easy to use and professional. Awesome app altogether

My favourite app
As a young birdwatcher who was always keen to be apart of a community but never seemed to find one, my problem was solved downloading this!!! Everyone is so friendly and just as excited to see birds as me 😁

Recommend for any bird watcher
Very wholesome app: I joined this app with a new interest in watching birds to help me find out what I was spotting. The community is very active in helping identify birds which is great and everyone is very kind so it’s just a nice wholesome community. I would definitely recommend this for any bird spotter πŸ˜ƒ
