Onthophagus
haematopus Harold 1875 fue la especie dominante, lo que concuerda con la literatura, donde la citan como una especie bien representada en los bosques amazonicos (Quintero & Halffter, 2009).
De acuerdo a estas caracteristicas del habitat, las especies de aves que visitan la isla realizaban distintas actividades en estos sitios: se observaron aves reposando en litoral arenoso (Pelecanus erythrorhynchos, Pelecanus occidentalis, Phalacrocorax auritus, Sula leucogaster, Ardea herodias, Egretta thula,
Haematopus palliatus, Larus delawarensis, Larus heermanni, Larus livens, Leucophaeus atricilla, Hydroprogne caspia, Thalasseus maximus).

Australian Pied Oystercatcher
Haematopus longirostris
The north and north-eastward shift of the distribution range of species characteristic of western, south-eastern and southern Europe registered in Lithuania throughout the 20th century (great cormorant Phalacrocorax carbo, great white egret Egretta alba, mute swan Cygnus olor, common shelduck Tadorna tadorna, gadwall Anas strepera, common pochard Aythya ferina, tufted duck Aythya fuligula, pied avocet Recurvirostra avosetta, Eurasian oystercatcher
Haematopus ostralegus, whiskered tern Chlidonias hybridus, red kite Milvus milvus, collared dove Streptopelia decaocto, penduline tit Remiz pendulinus and European serin Serinus serinus) was probably mainly caused by impact of the climate change in Europe (Kurlavicius 2006; Zalakevicius 2007).
Sexing Eurasian Oystercatchers
Haematopus ostralegus from breast feathers collected when ringing.
While in some cases, like the zebra mussel, introduction of alien mollusks has wrecked havoc with local ecosystems, in this case, the clam has improved conditions for as least one species, the European oystercatcher,
Haematopus ostralegus ostralegus, which winters in Britain (Lincoln, 2007).
nor other birds (Surfbirds Aphriza virgata, American Black Oystercatchers
Haematopus bachmani) influenced acorn (or gooseneck) barnacles at BB or SH (Marsh 1986; B.
In order to obtain the longest possible study periods, data on the fecundity rate and adult survival rate in three species (Parus major, Ciconia ciconia, and
Haematopus ostralegus) were taken from two different populations.

Haematopus ostralegus, the impact of disturbance appears much lower with good feeding conditions.
