I saw the first White-eyed Vireo I have observed in Florida today.

This species is considered a highly opportunistic feeder and food waste can make up to 70% of its diet.

Ring-billed Gulls, Herring Gulls, and Great Blue Herons reached their peak numbers during the late 1980s and have declined slowly since (Blokpoel and Tessier, 1998; Morris et al., 2003; Morris et al., 2009).

However, Ring-billed Gulls do better than many gull species and will often raise two chicks to flying age—five to six weeks.

October 7 - Longevity record: On May 20th, our field crew live caught a Ring-billed Gull on the Deslauriers colony near Varennes that was 27-year old!

In the last 50 years or so, Ring-billed Gulls have reoccupied most of their former breeding territory in the northern United States and southern Canada.

Researchers from UQAM and other Quebec universities then proposed to design a research project to study the behaviour of Ring-billed Gulls in urban and suburban areas within an integrated management framework.

This gull is a regular wanderer to western Europe, and in Ireland and Great Britain it is no longer classed as a rarity, with several birds regularly wintering in these countries.

The two species nest in similar habitat and Ring-billed Gulls return on spring migration more than a month ahead of the terns and often take over their nesting sites.

After a rapid demographic explosion during the 1970s and 1980s which culminated in 1991, (Canadian Wildlife Service, unpublished data) the Ring-billed Gull population showed slow, consistent decline to 2006 (Figure 2).
