Subject: [cobirders] Colorado Rare Bird Alert for March 20, 2017
Hello cobirders,

Our report is called Rare Bird Alert because search engines find it
better. The report is really "Uncommon Bird Report" Not all uncommon
birds are rare birds. Birders may want to know where to see them anyway!
Without being a member, "cobirders" can be read at:

NOTE: Reports do not confirm sightings. Choose to chase at your own risk
and expense.!
NOTE: With the many reports coming in daily this spring, RBA will reflect
daily sightings, not long term sightings, visit Colorado Birding Society's
website everyday!
