Discussion for April 2018 

During the month I received an email from Owen Holt who wrote that he had seen the Greater Roadrunner run across the road near the Grant Lake parking lot on 16-February, which is an earlier date than I had recorded. So, I’ve made that revision.
 
We had 18 new birds in April, bringing the total count to 243. The average new birds found in April is 21, while the average total bird species recorded through April is 243. The new birds for April, with rarity codes in parentheses were:
