May has been another busy month of data collection for team MacroBird with us reaching some big milestones on both the photography and 3D scanning sides of the project.
We also collaborated on a short video exploring the immense value of museum collections with the brilliant team at Eco Sapien– an organisation dedicated to spreading the word about all things related to biodiversity, conservation and the natural world. You can view the video, featuring our very own Dr Chris Cooney and a cameo from Emma Hughes, here:
Data Collection in Tring: 3D Scanning
Last week we celebrated reaching 80% of all bird species processed- that’s over 8000 specimens selected, retrieved from the collections and, where possible, databased, measured and 3D imaged! You can view many of these scanned species (approaching 7000) on our MarkMyBird gallery.
As with last month, we have continued to work on completing scanning the bills of all island species such as the fantails (Rhipiduridae) with their flat, triangular bills, and the bristly drongos (Dicruridae). Just to make life easier for ourselves, we have also turned our attention towards working through some of the remaining families with particularly hard to scan bills, such as the sunbirds (Nectariniidae) and hummingbirds (Trochilidae). With extremely fine tips, prominent bristles and long bills- such as the Streaked Spiderhunter (Arachnothera magna) pictured here- these species are time-consuming to both scan and select from the collections.
To date we have scanned:
- 6994 (69.99%) of species
- 3281 (80.97%) of species from island families
- 3788 (63.33%) of passerines
- 3203 (79.54%) of non-passerines
Data Collection in Tring: UV and Visible Photography
Plumage photography has continued at full pace and also reached some important milestones with well over 10,000 individual specimens now imaged- a huge achievement!
Amongst other families this month we have been photographing the beautiful Paradise Flycatchers, part of the monarch (Monarchidae) family. Found across Africa and Asia, the genus Terspiphone is sexually dimorphic- with colourful males featuring prominent tail streamers and primarily monochrome or rufous females.
Another interesting feature exhibited by some species within this family are colour morphs. For example, the male Madagascar Paradise Flycatchers (Terpsiphone mutata) have both a nominate white morph and a rufous morph.
To date we have reached:
- 67 (34.54%) of families completed
- 2452 (24.54%) of species
- 11209 specimens: we are selecting up to 6 specimens of each species, both male and female
- 67254 photographs: six photographs- dorsal, ventral and lateral in both UV and human visible spectrums- of every selected specimen
Mark My Bird
Our crowdsourcing site markmybird.org has now exceeded 820 registered landmarkers. With over 5000 3D bill models uploaded and ready for landmarking, and more added regularly as each family is scanned from museum specimens, there is lots to be done! If you would like to see the amazing diversity of bill form up close, you can visit our site markmybird.org and have a go at landmarking, contributing directly to this huge study.
If you are new to citizen science, aren’t sure what we mean by landmarking or just want to see the process in action, Elliot has also produced a video taking you step-by-step through the landmarking process. Any questions, queries or comments- let us know!
Twitter and #BeakoftheWeek
Our twitter competition #BeakoftheWeek has continued every Wednesday- all are welcome to join in and have a guess, perhaps even beating our current contenders to the top slots!
We post regular blogs about some of our favourite species chosen for the weekly challenge over on our website, this month including the fascinating Tawny Frogmouth (Podargus strigoides).
RAs Zoë, Emma, and Elliot wrote an article for the Spring edition of the Natural History Museum’s evolve magazine. Exploring the role of the museum’s collections and citizen science in our research, the article includes photographs of some of our favourite unusual bills from the ornithology research collections taken by Chris and Lara.
Zoë is also lead author on a paper detailing the rediscovery and identification of a (thought to be) long lost owl specimen collected by Charles Darwin on the famous second voyage of HMS Beagle. During research into the zoological collection of Robert FitzRoy- Darwin’s captain during the South American voyage- a specimen thought to be Asio flammeus galapagoensis was found to contain a tiny metal tag hidden amongst its tarsal feathers indicating a different species and backstory. The paper explores how, by tracking a specimen through original voyage manuscript data and on through historical museum registers and catalogues, specimens such as this can be traced back to their original collectors and correct identifications.
