Miscellaneous Notes
- Lesser Black-backed numbers begin to build in coastal Florida in October. On 17 October 2016, Michael Brothers observed F:003 in Volusia County, FL. This individual, banded on 20 March 2015 in the same county, is more evidence that Florida's growing LBBG population exhibits some winter site fidelity.
- Putative Chandeleur Gulls (Kelp x Herring hybrids) have not vanished from the earth. October has become the month that these hybrids are reported with more frequency, especially on the Gulf Coast. Two were recorded this month (Indiana and Alabama) with a third candidate in Texas (Galveston County; 12 Oct 2016). Note that roughly 30 hybrid types were found back on the islands in the breeding season of 2015. I do wonder why more pure Kelp Gulls are not being reported in the ABA area. Perhaps some are being overlooked as large Lesser Black-backs, or, most are programmed to "winter" south of the equator.
