“…Several studies investigate these pollutants in eggs or feathers of seabirds (Khademi et al, 2015 ; Kitowski et al, 2018 ; Lam et al, 2005 ; Thongcharoen et al, 2018 ; Zolfaghari et al, 2007 ). For example, a study conducted in the Gulf showed high contamination of TEs (As, Cd, Co, Pb, Ni, Se and V) in eggs of O. anaethetus , and S. bengalensis (Khademi et al, 2015 ).…”

“…Aquatic avifaunal communities are particularly exposed to various pollutants and, due to ecological habits, can accumulate high levels of TEs in their tissues and eggs (Khademi et al, 2015 ). In addition, negative effects on offspring were observed in embryonic development and hatching success, linked to the presence of TEs such as Cr, Pb and Cd in avian species such as mallard (Thongcharoen et al, 2018 ). Moreover, seabirds, which accumulate TEs in nesting and feeding sites, may act as bio-vectors of TEs whose efficacy varies with trophic position (Michelutti et al, 2010 ).…”

In the Arabian Gulf (called also Persian Gulf; hereafter 'the Gulf'), Jana and Karan Islands are recognized as one of the most Important Bird Areas in the region. Many migratory breeding seabirds, like the Greater Crested Tern Thalasseus bergii, White-cheeked Tern Sterna repressa and Bridled Tern Onychoprion anaethetus, depend on these islands during the breeding season. However, these aquatic wildlife species are suffering from intensified urban and industrial coastal development and various contamination events including wars and related oil spills. In this study, we used these three piscivorous top predator birds to analyse the levels of 19 trace elements (TEs; i.e. Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, Pb, Sr, V and Zn) in 15 muscular tissue samples from Jana and Karan Islands. PERMANOVA analysis showed no difference in contamination profile between sites nor between species probably due to their spatial and ecological proximity and therefore similar levels of exposure to TEs. Comparing these levels with existing literature, our results showed no particular concern for all elements, except for Al (maximum values recorded = 116.5 µg g−1 d.w.) and, in two samples, Ba (33.67 µg g−1 d.w.) and Pb (5.6 µg g−1 d.w.). The results can be considered as an initial step for supplementary evaluations with a larger number of samples and specified time intervals for the collection of specimens. This study provided baseline information on the pollution status of these two ecologically important sites which require a continuous biomonitoring programme.

“…The species' foraging behavior, which involves consuming contaminated prey or exposure to polluted habitats, may contribute to the higher exposure to lead (Shivanna, 2020). Primary feathers location and proximity to the external environment during flight and foraging activities likely contribute to lead accumulation (Thongcharoen, Robson, & Keithmaleesatti, 2018). Lead poisoning can lead to profound health issues, manifesting as conditions like depression, paralysis, leg or wing weakness, and neurological harm, including damage to the brain (encephalopathy) (Varagiya, Jethva, & Pandya, 2022).…”

The constant usage of trace elements in the environment can elucidate harmful health effects on sensitive species i.e. Birds residing on higher trophic levels. The current study is to investigate and compare toxic trace elements. accumulation patterns. Cd, Cr, Pb, Cu, As, and Hg in Remiges (Primaries, Secondaries, Tertiaries), Contours (body), and Rectrices (tail) feathers of Bubulcus ibis (Cattle Egret) sampled from Lahore, Pakistan. Pb, Cd, Cu, and Cr were detected with variable concentration levels; Hg and As were not detected in the study. The general trend is Pb>Cd>Cu>Cr trend among the Remiges, Contours, and Rectrices of Bubulcus ibis. Primaries Flight feathers showed the highest concentrations of Pb, followed by Cd, the minimum (min-max) concentrations of Pb, Cd, Cu, and Cr at 0.49(0.48-0.55), 0.23(0.07-0.43), 0.13(0.12- 0.14), 0.07(0.03-0.21), were observed in Contour, Tertiaries, Tertiaries, and Primaries feathers respectively. The values of elements were found non-significant (all P>0.05) in different feather types of Cattle Egrets, reflecting their similar distribution. Principle Component Analysis (PCA) based on co-relation matrices also depicted the homogenous distribution of toxic trace elements among different feather types. Compared to previous studies from or near to study site, the current study depicts a relatively lower level of toxic trace metals, which are unanimously distributed among different feather types of cattle egret. However, their environmental presence has significant health consequences for Pakistan's already diminishing avifauna.

“…Cattle egret, Bubulcus ibis, is a resident wild bird which could be used as a reliable ecological indicator of atmospheric pollutants because it is resident, widely distributed in different habitats and closely associated to human activities (Thongcharoen et al, 2018).…”

Different heavy metals accumulate in the environment due to intensive human activities, which adversely affect wildlife. Biota usually develops different biological responses to face such stress; analysis of these biological responses could be used as a biomarker of pollutants. The current study aimed to compare hematologic and biochemical parameters in cattle egret collected from industrial and rural sites in New Damietta City, Egypt, to assess the effect of heavy metal pollution. Selected heavy metals concentrations including copper (Cu), cadmium (Cd), zinc (Zn), lead (Pb), nickel (Ni), arsenic (As), and mercury (Hg) were measured for the two sampling sites in aerosols from ambient air, feathers, and blood samples. Some hematological, biochemical parameters and oxidative stress markers were measured in the blood using a non-invasive method. Sampling was done in summer and winter during 2015-2016. Heavy metal concentrations in aerosols from the industrial area were significantly higher than those from the rural site. The highest concentrations of all heavy metals in both sites were recorded in summer. Cattle egret from the industrial area showed a significantly decreased RBCs count and PCV level and increased WBCs count, total protein, albumin, triglycerides, uric acid, ammonia, creatinine, bilirubin, and cortisol levels. Moreover, birds from the industrial area suffered from environmental stress as indicated by elevations of MDA, GPx and catalase activity in industrial birds as compared to rural birds. In conclusion, birds from the industrial areas were adversely affected by the elevated concentrations of selected heavy metals, so it could be used as an effective bioindicator of environmental contamination.
