The main species of gull that nest on roofs and dwellings are the Herring Gull and the Lesser Black Backed Gull, they are very similar in size and appearance the main distinguishing factor is the herring gull has pink legs and the Lesser Black Backed Gull has yellow legs , very rarely a Greater Black Backed Gull will be found.
Research has proven that, generally, gull pairs will accept and carry on incubating dummy eggs. Plastic eggs part filled with sand can be painted to look like gull`s eggs. These are then substituted for the real thing.
As well as cutting down noise, dummy eggs may slowly disperse the colony. Females who fail to breed will find a new mate and therefore nest elsewhere (this could of course be an adjacent roof.) Also it is thought that male birds may return to their original colony, so in 3 years’ time there could be fewer birds returning to your area
