| heavy metal and selenium levels in feathers of young egrets and herons from hong kong and szechuan, china. | several species of herons and egrets frequently nest in colonies in areas where humans also concentrate. since the birds feed on intermediate-sized fish that themselves concentrate pollutants, they can be used not only to assess the levels of contaminants in avian tissues but as indicators of contaminants in the environment. the concentration of heavy metals and selenium in the breast feathers of fledgling black-crowned night herons nycticorax nycticorax and chinese pond herons ardeola bacchus f ... | 1993 | 8215588 |

| polychlorinated biphenyls and organochlorine pesticides in local waterbird eggs from hong kong: risk assessment to local waterbirds. | the contamination status of the marine environment in hong kong was studied by measuring concentrations of organochlorine (oc) pollutants (i.e., hexachlorobenzene, aldrin, dieldrin, endrin, mirex, total heptachlor, total chlordane, total ddts, total pcbs, and total toxaphenes) in the eggs of selected waterbird species from different locations around the city: little egret (egretta garzetta) and chinese pond heron (ardeola bacchus) from mai po village, great egret (ardea alba) and black-crowned n ... | 2011 | 21440927 |
| polychlorinated dibenzo-p-dioxins (pcdds), polychlorinated dibenzofurans (pcdfs), dioxin-like polychlorinated biphenyls (pcbs) and polybrominated diphenyl ethers (pbdes) in waterbird eggs of hong kong, china. | concentrations of pcdd/fs, pcbs and pbdes were measured in 56 egg samples collected from waterbirds of different species (great egret, little egret, night heron and chinese pond heron) from different regions of hong kong (ho sheung heung, mai po village and mai po lung village) during 2000 and 2006. dominance of 2,3,4,7,8-pecdf indicates a signature associated with commercial usage of pcbs. although no significant variations were observed within- and between-site in the levels of pcdd/fs, coplan ... | 2012 | 22024097 |
| the complete mitochondrial genomes of sixteen ardeid birds revealing the evolutionary process of the gene rearrangements. | the animal mitochondrial genome is generally considered to be under selection for both compactness and gene order conservation. as more mitochondrial genomes are sequenced, mitochondrial duplications and gene rearrangements have been frequently identified among diverse animal groups. although several mechanisms of gene rearrangement have been proposed thus far, more observational evidence from major taxa is needed to validate specific mechanisms. in the current study, the complete mitochondrial ... | 2014 | 25001581 |
| assessment of organochlorine pesticide contamination in waterbirds from an agricultural region, central china. | twenty-one organochlorine pesticides (ocps) were measured in the muscle of six predominant waterbird species from jianghan plain, hubei province, central china. among ocps, ddts were the most prevalent compounds, with average concentration ranging from 31.1 to 1445 ng/g lipid weight. little egrets (egretta garzetta) and chinese pond herons (ardeola bacchus) showed significantly higher concentrations of ocps (p < 0.05) due to their dietary habits and migratory patterns. there were no statisticall ... | 2016 | 27783194 |

| egg recognition and chick discrimination in colonial breeding birds. | theory predicts that parents will not raise unrelated offsprings. for colonial breeding birds, evolving an ability to recognize their own eggs and chicks can prevent misdirecting parental behaviour. to verify this hypothesis, egg recognition experiments were performed on colonial breeding chinese pond herons (ardeola bacchus) and cattle egrets (bubulcus ibis) in chengmai and lingao, tropical hainan island, china. furthermore, a chick discrimination experiment was conducted on chinese pond herons ... | 2019 | 31493492 |
