Below: An immature Gambel's White-crowned Sparrow (Z. l. gambelii) found west of Butlertown, Kent Co., Maryland (2/25/2007). According to the MD/DCRC database, there are four accepted records of this subspecies, with a number of others recirculating or reviewable. There are 20 total reports starting in 1944, then jumping to 1961 and 1965. Starting in 1999, reports of the subspecies have been annual. Nine of the reports are from Chino Farms in Queen Anne's Co., which I'd assume are mostly of banded individuals. Reports are from as early as October 3rd to as late as May 7th.

Below: An immature Eastern White-crowned Sparrow (Z. l. leucophrys) at the same location for comparison (2/25/2007). The plain lores on the Gambel's is probably the easiest field mark to observe.

Below: A Gambel's White-crowned Sparrow at Chesapeake Farms, Kent Co., Maryland (11/9/2007). Interestingly, many of the state's records of this
subspecies come from this part of the state. This was my second in the state; the other was just a couple miles away on 2/25/2007 with Jim Brighton.

Below: Here's an Eastern White-crowned at the same location for comparison. Note especially the dark lore. This field mark
stands out even more in most Eastern individuals. Note that the Gambel's doesn't have even a suggestion of dark in the lore.

Below: An adult Gambel's White-crowned Sparrow at Prime Hook NWR, Delaware (3/2/2008). This appears to be the first
documented record for Delaware.

Below six: Some Eastern White-crowned Sparrows at Prime Hook NWR, Delaware (3/2/2008). I've been meaning to add more of our Eastern White-crowns for comparison to recent Gambel's.
