The post yesterday, I.O.C. 9.2 Update A Few Days Ago, was to inform you off the latest update. New birds aren’t usually discovered as much as the DNA studies they are providing better insight into how the birds are related. So, they like to shuffle things around, like the 5 new Families. The new species added are many times from subspecies being elevated to full species status.

Today, we will try to figure out who the new species are. As I type this, I have no clue until some investigation begins. So, Let’s Begin!

Version 9.2 (June 22, 2019)

The IOC World Bird List 9.2 contains 10,758 extant species (and 158 extinct species)  classified in 40 Orders,  250 Families and 2,320 Genera.  The list also includes 20,034 subspecies, their ranges and  authors.

Updates include:

SPECIES ADDED:                25 

SPECIES DELETED:             5

ENGLISH NAMES:              9

TAXONOMY:                         37 including  sequence of Orders,  five new Families, and genera of  Petroicidae

“He determines and counts the number of the stars; He calls them all by their names. Great is our Lord and of great power; His understanding is inexhaustible and boundless.” (Psalms 147:4-5 AMP)

If the Lord knows the names of all the stars, I wonder what names He calls the Birds by?

Still need to rework the Indexes – Stay Tuned

First Family Page Completed – Ardeidae

I just completed the first Birds of the World Family page. Well, at least as far as I can find photos for it. I now only have 223 more family pages to go.

Check it out at Family – Ardeidae It is part of the PELECANIFORMES Order. At least according to the latest IOC 2.1 version. I hope you enjoy the photos of the different Bitterns, Egrets and Herons.
