Shorebirds from Two Hemispheres
The lovely bird above is the Southern Lapwing, it is a widespread species that breeds across most of South America. While considered non-migratory, in recent years, the Southern Lapwing has steadily spread it's range through Panama, to Costa Rica, and through the Caribbean to the Lesser Antilles. Extralimital reports have come from Mexico and Belize as well. So clearly this resident has some migratory tendencies.
There have been some controversial sightings of Southern Lapwing in the US, mostly in Florida, that have caused a stir in the birding community. Nearly all of these reports, come from late spring - early summer in the Northern hemisphere (28 April, 21 May, 1 June, 2 June, 17-25 June, and 23 July). Many experienced tropical birders speculate that this is a time when other southern hemisphere (austral) breeders would be moving North for the Austral winter. Further, when coupled with the aforementioned range expansion, many (myself included) feel that some of these birds are likely true wild vagrants that are overshooting their winter range and finding their way to North America on their own. However, the Florida record committee, continues to maintain that all (so far) have to be written off as escapees from captivity since the primary literature suggests these are non-migratory birds. Debating origin on birds outside their normal range is always fun, but whether acccepted as wild or not, it is possible that before long this lovely shorebird could have a foothold in southern North America as well!
