The female Pitcairn Angel (Genicanthus spinus
) is exceedingly rare, and is certainly one of the only, and possibly the first-ever, in trade.
One species was recorded only in mixed oak-pine forests (Eurasian Siskin Spinus spinus
; at one point count), six species were found only in oak woodlands and 17 species were found only in pine woodlands (Table I).
The four Swiss accounts from 1968 were closed in February 1970 and the funds transferred to a 'Xandy Foundation' that later grew and morphed into foundations under the names Wintrop, Charis, Scolari, Valamo, Spinus
, all of which ended up in a consolidated account known as the Avertina Foundation.
Clinical and subclinical toxoplasmosis have been observed in pigeons and other avian species like Passeriformes including canaries (Serinus canarius), greenfinches (Carduelis chloris), goldfinches (Carduelis carduelis), sirkins (Carduelis spinus
), Linnets (Carduelis cannabina), bullfinches (Pyrrhula pyrrhula), Hawaiian crow (Corvus hawaiiensis), satin bowerbirds (Ptilonorhynchus violaceus), regent bowerbirds (Sericulus chrysocephalus), and red-whiskered bulbuls (Pycnonotus jocosus) .
Similarly, Mateos-Gonzales and Senar (2012) found in siskins (Carduelis spinus
) with larger and darker bib coloration, latency to approach a novel object was reduced.
The most numerous species were yellowhammer (Emberiza citrinella) (10.7 % of all individuals), fieldfare (Turdus pilaris) (9.4 %), great tit (Parus major) (6.3 %), house sparrow (Passer domesticus) (5.5 %) and Eurasian siskin (Carduelis spinus
) (5.1 %).
For both of these birds, as well as goldfinches, (Spinus
tristis), purple finches, (Car-podacus purpureus) and many sparrows (Pas-seridae), the scrub provides the necessary type of roosting and nesting site.
