Calidris pugnax

This species is found only rarely in the spring (the best time is the final third of May) and there is a single early summer record in late June. It is found much more commonly as a southbound migrant with occasional records starting during late summer in the first week of August. By August 15th this species has become much more reliable with a peak in occurrence from August 20th to September 1st when this species is annual. By September, migrants become rare again with few arrivals during the month and only a couple records after September 15th.
