@grrlscientist great article about recent #research on the #eggmimicry in #cuckoos with fascination information about the number of distinct #eggvariations a cuckoo female can produce to be able to mimic as #broodparasite a greater diversity of #hostspecies. Fascinating are especially the findings about the genetic basics for all that in the European cuckoo.
