Alien Species

1. Corvus splendens (bird)    

The house crow (Corvus splendens) has established itself in at least 25 countries. It proliferates in human settlements and disturbed habitats and is especially suited to coastal settlements. It can even penetrate harsh desert environments once man has become established there. The house crow causes problems across a range of areas, including crop and livestock sustainability and poses a risk to native avifauna. It also carries a range of human pathogens but a link with human disease is yet to be established.

Common Names: bæjakráka, Ceylon crow, Colombo crow, corbeau familier, cornacchia grigia indiana, corneille de l'Inde, corneja India, corvo delle case, cuervo casero, domaca vrana, gagak rumah, Glanzkrähe, gralha-indiana, grey-necked crow, Hauskrähe, hint kargasi, huiskraai, huiskraai, huskrage, huskråka, huskråke, iegarasu, Ie-garasu, Indian crow, Indian house-crow, Indijine varna, intianvaris, Kunguru Bara-Hindi, maniyan kakai, nalla kakka, õuevares, préachán binne, town crow, vrána domácí, vrana lesklá, vrána lesklá, wrona orientalna

2. Passer domesticus (bird)      

Passer domesticus (the house sparrow) is a small bird, native to Eurasia and northern Africa, that was intentionally introduced to the Americas. Passer domesticus are non-migratory birds that are often closely associated with human populations and are found in highest abundance in agricultural, suburban and urban areas. They tend to avoid woodlands, forests, grasslands and deserts. Particularly high densities of Passer domesticus were found where urban settlements meet agricultural areas. They may evict native birds from their nests and out-compete them for trophic resources. Early in its invasion of North America, Passer domesticus began attacking ripening grains on farmland and was considered a serious agricultural pest. Recent surveys indicate populations are declining.

Common Names: English sparrow, Europese huismuis, gorrion casero, Gorrion domestico, house sparrow, house sparrow, moineau domestique, town sparrow

Native Species

1. Estrilda astrild (bird)

         Interim profile, incomplete information

The common waxbill, Estrilda astrild is native to tropical and southern Africa, but has been introduced to many island nations where it has shown mixed success in establishment. It feeds mainly on grass seeds and is commonly found in open long grass plains and close to human habitation. E. astrild shows a high reproductive rate which is attributed to its ability to naturalize easily.

Common Names: avadavat, common waxbill, red-cheeked waxbill, waxbill

2. Porphyrio porphyrio (bird)

The ecological similarity of the purple swamphen (Porphyrio porphyrio) to the Florida native common moorhen (Gallinula chloropus) and purple gallinule (Porphyrula martinica) have prompted efforts to eliminate this member of the rail family from Florida. It is not clear what negative consequences could result from these non-native birds but in other parts of the world they are noted for their aggressive behaviour and their habit of eating other bird's eggs.

Common Names: bláhæna, caimão, calamón común, Modrzyk, pollo sultano, pukeko, purperkoet, purpurhöna, Purpurhuhn, seikei, slípka modrá, sultanhøne, sultanhøne, sultánka modrá, sulttaanikana, talève sultane
