Discussion for April 2019

Before I report on April, I have an addition to January, a Ring-necked Pheasant found on 20-January by Brooke Miller near Coast Casey Forebay. That brings the total at the end of March to 224. There were 18 new birds found in April (21 is the average), for a total of 242 birds (average is 243) at the end of April. Thank you to everyone who birded, and took the time to report birds either on SouthBayBirds, eBird, or send emails directly to me.
