And God said, Let the earth bring forth the living creature after his kind...
Genesis 1:24
"There is little in nature to compare to the beauty of bird song.
For
this, birds use a unique avian vocal organ called the syrinx in the
chest at the bottom of the trachea (windpipe). 
Birds also have a larynx
in the throat at the top of the trachea, and other animals use this
‘voicebox’ to make sounds. But birds use only their syrinx to vocalize.
A
new study trying to identify its evolutionary origin has come up short,
confirming the syrinx is unique to birds, an evolutionary oddity.
Most evolutionists say that birds evolved from dinosaurs. But the
origin of the syrinx is squarely at odds with this notion, as no
dinosaur has been found with a syrinx.
Rather, the ‘oldest’ known
fossilised syrinx was found in a fully formed bird, the fossils of which
are found with dinosaurs—Vegavis iaai, a member of the duck/goose created kind.
In short, said Chad Eliason, a co-author of the study, “We don’t know
where that organ came from, how and why it evolved”.
We read in Genesis that birds were created according
to their kinds on Day 5. This would have been complete with the syrinx,
able to produce the majestic sounds God created them to make." CMI
