Painted Bunting, Boy Scout Woods, High Island, TX
In prevailing conditions, most leave the Yucatan in the evening and arrive on the Texas coast the next day. Many do not stop, but continue further north to the woods of East Texas or beyond.

However, a strong cold front crossing the coast can subject the migrants to adverse headwinds and turbulence. The exhausted birds "fall out" on the immediate coast.
Other birders have told us about days past when birds covered the ground and filled the bushes, seemingly unaware of human and other dangers. Alan Tennant in his book On the Wing gives a particularly vivid description of the "fallout" at High Island, TX and the carnage produced by speeding vehicles on the coastal highway.
Kentucky Warbler, Hooks Woods, High Island, TX
In the past three years we have enjoyed birding the spring migration at High Island, TX. But, we have seen nothing that matches the passage in Tennant's book, or the descriptions of the fallouts of past decades by other birders.
Golden-winged Warbler, Boy Scout Woods, High Island, TXThis Spring, there were some days when various warblers, thrushes, oreoles, etc. were relatively abundant. However, there were few days with strong cold fronts or significant northerly winds. The "good news" in this is that migrant mortality is probably lower proportionately than in the past. The "bad news" is that the few birds seen are only the remnants of once more abundant populations . This is due to an overwhelming loss of habitat in breeding and in migration stop-over sites under inexorable "development". The "human glacier that now bears down on every continent of the world" in Alan Tennant's metaphor.

 Cerulean Warbler populations, for instance, have fallen to less than 1/5th of what they were 40 years ago. Wood Thrush populations apparently show a long term average decline of 1.7% per year.
