ABSTRACT Research on water birds family, Ardeidae, was done in Delta Solo Ujung Pangkah Gresik, and the aim of the research was to know the occurrence of the Ardeidae species, it abundance, dominance, and diversity. Concentration count was method used to collect species data and its abundance. Five difference stations were observed to collect data, and binocular, field telescope, and handy counter were use in this observation. In each station observations were done six time which was 30 minutes duration for each, and two hours interval. For species identification a field guide book by MacKinnon et al., 1999 was used. Relative abundance was used to calculate domination index and similarity index between pairs among the five stations were calculated according to Oosting index, and Shannon Weaver index was used to know the species diversity index. The result of this research as follow: 12 species of Ardeidae were identified in this area, they were: Ardea cinerea, Ardeola bacchus, Ardeola speciosa, Bulbucus ibis, Butorides striatus, Egretta alba, Egretta garzetta, Egretta intermedia, Egretta sacra, Gorsachius melanolophus, Jxobrychus sinensis, and Nycticorax nycticorax, the higher dominance's index was Egretta garzetta (42,27%), other wise among 12 species five species had lowest one (0,26%). Among the Ardeidae species in the observed area the most dominance were Egretta gar::etta, Ardeola speciosa, and Egretta alba. The diversity indices of the five stations were between 1, 116 to 1,386, it indices the diversity was low. The diversity in the mudflats was higher than in the mangrove and fishponds. The higher similarity between pairs among the five stations was found between station II and station III (65,12%), but for all five stations the similarity was 41,80%.

ABSTRACT 
Research on water birds family, Ardeidae, was done in Delta Solo 
Ujung Pangkah Gresik, and the aim of the research was to know the occurrence of 
the Ardeidae species, it abundance, dominance, and diversity. Concentration 
count was method used to collect species data and its abundance. Five difference 
stations were observed to collect data, and binocular, field telescope, and handy 
counter were use in this observation. In each station observations were done six 
time which was 30 minutes duration for each, and two hours interval. For species 
identification a field guide book by MacKinnon et al., 1999 was used. Relative 
abundance was used to calculate domination index and similarity index between 
pairs among the five stations were calculated according to Oosting index, and 
Shannon Weaver index was used to know the species diversity index. The result 
of this research as follow: 12 species of Ardeidae were identified in this area, 
they were: Ardea cinerea, Ardeola bacchus, Ardeola speciosa, Bulbucus ibis, 
Butorides striatus, Egretta alba, Egretta garzetta, Egretta intermedia, Egretta

the higher dominance's index was Egretta garzetta (42,27%), other wise among 
12 species five species had lowest one (0,26%). Among the Ardeidae species in 
the observed area the most dominance were Egretta gar::etta, Ardeola speciosa,
