checking pubmed for influenza and sparrows:
----------------------------------------------------------------------------------
LPAIV H3N8
Oropharyngeal shedding was short lived, and was detected in more
starlings (97.2%) than sparrows (47.2%; n=36 of each).
Cloacal shedding was rare in both species (8.3%; n=36 of each)
and no cage-mate transmission occurred
50% of these individuals seroconverted by 5 d.p.i., and nearly
all birds (97%; n=35) seroconverted by 28 d.p.i.
In general, pre-existing homologous immunity led to reduced shedding
and increased antibody levels within 7 days of challenge
... passerines are not significant reservoirs
--------------------------------------------------------------------------------
HP H5N1 A/duck/Laos/25/06
sparrows and chickens.
Inoculated birds shed virus at high titers from the oropharynx and cloaca, and infection was fatal.
Waterborne transmission from inoculated sparrows to contact chickens was absent,
while 25% of sparrows were infected via waterborne transmission from chickens.
The viral shedding and susceptibility to infection we observed in sparrows,
coupled with their presence in poultry houses, could facilitate virus spread
among poultry and wild birds in the face of an H5N1 influenza virus outbreak.

A/tree sparrow/Jiangsu/1/08) genotype V A/Jiangsu/1/07 (H5N1),

A/whooper swan/Mongolia/244/05 (H5N1
house sparrows were highly susceptible
excreted virus via the oropharynx and cloaca for several days prior to the onset of clinical signs
pigeons were resistant duration of viral shedding was brief, and viral titers were low

Rostow-region,2007:
RT-PCT revealed influenza virus A/H5 in 60% of pigeons and crows and in around
20% of starlings and 10% of tree sparrows
Fifteen viral strains from chickens (Gallus gallus domesticus),
Indian ducks (Cairina moschata), rooks (Corvus frugilegus),
rock pigeons (Columba livia), tree sparrows (Passer montanus),
common starlings (Sturnus vulgaris), and great white herons (Egretta alba) were isolated
----------------------------------------------------------------------
Sparrows were susceptible to severe infection; 66%-100% of birds died within 4-7 days. High levels of virus were detected from oropharyngeal and cloacal swabs and in organs of deceased sparrows. Inoculation of starlings caused no deaths, despite high levels of virus shedding evident in oropharyngeal swabs. Least susceptible were pigeons, which had no deaths and very low levels of virus in oropharyngeal and cloacal swabs. Transmission to contact birds did not occur frequently: only A/common magpie/Hong Kong/645/2006 virus was shown to transmit to 1 starling.

zebra finches (Taeniopygia guttata), house finches (Carpodacus mexicanus),

and budgerigars (Melopsittacus undulatus) after intranasal administration.
Zebra finches were the most severely affected of the five species,100% mortality

house sparrows suffered only mild transient depression
Starlings demonstrated no clinical disease

Of 927 sera taken from poultry from 84 flocks, 33% proved seropositive
Notable high infection rates were found among Anatidae (43%),
flamingoes (43%) and sparrows (31%); the latter species may play an
important role in carrying the disease from its natural reservoirs to domestic farms

A/sparrow/Ukraine/83
A/sparrow/Ukraine/83 was isolated from a member of synanthropic birds, a tree sparrow, near Kanev. This virus showed low pathogenicity and immunologic activity in experimental infection of sparrows and other birds. Sera from a number of avian and mammal species had antibodies to this virus which indicates that synanthropic and semi-synanthropic birds may be a connecting link in spread of influenza virus.
