Career
He wrote numerous books about birds and bird identification. Makatsch was a staff member at both the Heligoland and Rossitten Bird Observatories. In 1967 he presented in his work Kein Ei gleicht dem anderen, "Number egg is like another", the surmise, that the colour white is the colour of the evolutionarily oldest eggs (white is the colour of reptile eggs).
Only the need to camouflage the eggs against predators led to a change in colour of the eggs.
Wolfgang Makatsch traveled extensively, collecting on his expeditions more than 30,000 eggs. This collection is one of the largest in Germany and currently in the Staatliches Museum für Tierkunde Dresden.
