Collaborative List – March 2019

Are we all getting excited yet? March is done. The equinox has passed. There can be no denying that spring is coming and with it, the summer visitors and passage migrants. Oh, joy!

9 countries were visited during March by your tireless beats (11 of them); India, UK, USA, Serbia, Costa Rica, Japan, Australia, Singapore and Malaysia. With so much thrashing around in SE Asia, it is interesting to compare east and west hemispheres. Whilst the eastern hemisphere still leads the life rankings by 1991 to 1808, the western hemisphere outbirds by 877 to 705 in the 2019 list and 615 to 385 during March.

995 species were tallied this month from 165 checklists. The yearly total has reached 1538 while the life list has been pushed to 3676.

We can use the figures above to compare the birds that cross between the hemispheres. Only 123 species appear on both sides of the life list. That’s just 3.35%. 44 for the year list, which equates to 2.77% and 22, or 2.25% during March. So if you want to see something new, cross the Atlantic. It’s all weird over there!
