Apparently the availability of food from landfills is motivating an increasing number of White Storks to give the African migration a miss … see http://www.sciencedaily.com/releases/2015/02/150224083112.htm

No Philip, I don’t have the story wrong. I was referring to a different migration issue to the one mentioned in the story. The connection is that migration patterns can change. Regards, Laurie. On 27 Feb 2015, at 8:35 am, Philip Veerman < pveerman@pcug.org.au> wrote:

Laurie, I think you have the story wrong or are asking the question upside down. It is not that they are starting to breed in its winter habitat. The story inasmuch as I read it is that they are starting to migrate less to their winter habitat. That is they are not following the summer from Europe to the southern hemisphere………… Quick extract follows……….. Philip Despite suffering population decline in Europe, in Spain the white stork (Ciconia ciconia) is especially numerous and concentrated particularly in Castilla-La Mancha (with 11,723 birds) and Extremadura (with 11,190). However, the province of Cáceres is home to the largest population of storks, with 7,035 couples increasingly migrating less to Africa. “The storks stay over the winter in the Peninsula, as landfills have become a permanent source of food,” confirm the researchers from the Toxicology Unit of the University of Extremadura. —–Original Message—– Laurie Knight Sent: Thursday, 26 February 2015 9:14 PM Cc: Birding Aus It would certainly be one for the books if a inter-hemispherical migrant started to breed in its winter habitat.

G’day all European Bee-eaters breed near Cape Town. Others are non-breeding populations from Europe and they overlap at times. Presumably a few European individuals once migrated south far enough to find conditions suitable for breeding and stayed. According to HBW Alive (hbw.com) the southern African breeding birds migrate to Angola and the Democratic Republic of Congo (formerly Zaire) post spring-summer breeding. I saw birds breeding near Cape Town in late September 2006 and the European migrants in Tanzania from October 2010 to April 2011. Similarly there is a population of Black Stork that breeds in southern Africa that has probably established from overshooting European migrants. In this case there is almost certainly no mixing of southern African and migratory European breeding Black Storks. Any possible Australian examples? Cheers Steve

There were still a great number of them in Morocco a couple of weeks ago. It was a delight to see so many. Thankfully they are considered sacred in Morocco so they are completely safe to nest there it seems.

It would certainly be one for the books if a inter-hemispherical migrant started to breed in its “winter” habitat. On 26 Feb 2015, at 8:07 pm, Carl Clifford < carlsclifford@gmail.com> wrote:

Perhaps migration is not as hardwired in some birds as we think? Carl Clifford
