recentely new breeding siteof Platalea Minor in Russian federation was discovered Beside of a 5000 breedingpairs of leucorodias it was found that also some 20-30 Minors are breeding in Russia. North East. Remarkable is that most nearbij breeding poulation of the minors is over 6000 km.distance itvenenko2010)(ChinaHowever migration over a large distance was found also inPL. leucorodia from south spain(doñana) to north of theNetherlands (Waddensea)a distance of approx 2400 km. this mass migration was in 1996,probably due to drought in Spain and the dying of the nesting treesQuercus suber) spec.it was noticed that 1-3000 pairs migrated from Spain to Holland. At that moment approx half of theNWEuropeanbreedingpopulation migrated, the other half was breeding inscatterred sitesin surroundings of donana i.c. recentely new breeding siteof Platalea Minor in Russian federationBeside of a 5000 breedingpairs of leucorodias it was found that also some 20-30 Minors are breeding in Russia.

At that moment approx half of theNWEuropeanbreedingpopulation migrated, the other half was breeding inscatterred sites in surroundings of Coto donana i.c.south Portugal the mass migration probably not took place in one year but probably over 2-4 years Colourring readings proved this migration and its timing (O.Overdijk&C.Cañas, EDB 1996 in litt.)
coming weeks we make a tour along the french and spanish west coast, like we(my wife and I ) did since 1996visiting old friends and counting Spoonbills seperated(juvs and ad.apart) in order to get some insight in the reproduction

Group of people interrested in Spoonbills and assiociated waterbirds and their natural habitats coöperate and share their knowledge and experienceThis group was fondend in 2022 by Otto Overdijk (NL) and is expanded with people from UK France,Germany, Swiss, Spain ,Belarus Russia, Moldavia, FY, Turkey ,Greece,others will follow.
We also manage a colourring databases containing spoonbills ringed in NL, B. D.DK, Hungary, Greece,Croatia, czech-rep. Serbia, Turkiye, Uzbekistan,Iran Mauritania, Morocco, Portugal,France.
If some one want to report a sighting of such a bird, we will reply by sending ringing details and if availabel a life-history, send you sightings and or photo’s to mailto esa spoonbill@gmail.com alternatievely o.overdijk@knid.nl or o.overdijk@wxs.nl
many birds with transmitter die early, no bird live longer then 2 months techics are not very good and need improvements,especially the maner to attach the transmitter on the bird this is in many ocaissons wrongly attached see picture here above.juvenils with transmitter do not become to an age of being adult (4y.)scientist want to ad new functions to transmitters but for every new function capacity of power is needed. Batteries need therefore to expand which is not better (they become higher weight) for survival of the bird.also in 2025 many birds drop dead after short periode of running propperly this development is an concern not only in the netherlands also in Japan-Korea
