Hi Cobirders. Dog days does not come from heat suffering furry pets but rather Sirius,the brightest star in the sky, in the constellation Canis Major,
Alpha star. Canis is Latin for Dog thus Sirius is the Dog Star. and it reaches its furthest north in the southern sky in August . It brightness was thought
to add to August heat from Sol our sun. Of course the earth does not receive any heat from stars only light and guidance. OK I know Sol is a star.
So I will wait to August to come up with a few birds that may come to Colorado make 500 not counting splits.
Keep watching and look for Sirius if out late and it is clear.
