Seabirds are one of the most threatened bird groups on the planet, with approximately 30% at risk of extinction. The primary cause of population decline and extinction are non-native species introduced to islands, such as mammals, and which subsequently prey on seabirds or damage habitats. These “invasive species” are impacting 46% of seabird speci...

The number of active seabird restoration projects involving social attraction and translocation has increased rapidly in recent years and has helped seabirds reclaim some historical nesting areas and find safer nesting places in the face of increasing anthropogenic threats. An understanding of seabird ecology and breeding biology is essential to un...

The Baja California Pacific Islands (BCPI) is a seabird hotspot in the southern California Current System supporting 129 seabird breeding populations of 23 species and over one million birds annually. These islands had a history of environmental degradation because of invasive alien species, human disturbance, and contaminants that caused the extir...

San Benito Archipelago is internationally important for the conservation of 13 species of seabirds. San Benito Oeste, the largest and only inhabited island, was declared mammal-free in 2000 after a series of eradications conducted in collaboration between the fishing cooperative Pescadores Nacionales de Abulón, the Mexican conservation organization...

The endangered Ashy Storm-Petrel (Oceanodroma homochroa, ASSP) is a species with a declining population and a restricted breeding distribution in the Pacific Ocean. In Mexico, the Coronado Archipelago, off the Baja California Peninsula, is recognized as its only breeding colony, while knowledge about its biology and conservation needs is very limit...

The Least Storm-Petrel Oceanodroma microsoma is endemic to islands on both coasts of Baja California, in Mexico. It is the smallest seabird species and one of the least studied of the order Procellariiformes. We present a detailed account of its breeding success, chick growth, and diet at Islas San Benito, Baja California, during three consecutive...

During a survey of blood parasites in a population of Leach's and black storm petrels (Oceanodroma leucorhoa and Oceanodroma melania) in Mexico, infection by a Hepatozoon species in erythrocytes of several birds was noted. Here we describe the species as Hepatozoon peircei sp. nov. Some species of Hepatozoon described from birds have been identifie...

Abstract During a survey of blood parasites in a population of Leach and Black storm petrels (Oceanodroma leucorhoa and O. melania) in Mexico infection by a Hepatozoon species in erythrocytes of several birds was noted. Here we describe the species as Hepatozoon peircei sp. nov. Some species of Hepatozoon described from birds have been found to be...
