“…The concentration of Pb in feathers of cattle egret in this study is much higher compared to other studies in USA, Egypt, Turkey and Hungary [10,20,21,25,26], India [27] and Pakistan [6]. In the present study, there is no sampling point found less than 4µg/g which is harmful to birds [6].…”

Present study aims to determine the lead (Pb) concentrations in the feather samples of cattle egret (Bulbulcus ibis) found in different contaminated wetland habitats present in the state Odisha, India. This study also focused on the heavy metal concentrations of top layer soil and on the level of metal accumulation in prey samples (i.e. small fishes) preferred by cattle egrets for explaining the level of amplification of Pb in different polluted wetland habitats. Moreover, reasons behind the variations of Pb concentrations within the sampled wetland habitats are explained. Feathers, Prey samples and sediments from their foraging habitats were collected from eight different heronries. Determination of Pb concentrations in samples has undergone acid digestion followed by elemental analysis (i.e. Pb) in Atomic Absorption Spectrophotometer (AAS). The results indicated that Pb concentration was varied significantly in soil (15.13-56.26µg/g), Prey (0.21-55.76µg/g) and feathers (5.6-49.86µg/g) in different sites. The highest concentration was found at Hirakud in soil and prey. However, feather samples showed the highest concentrations of lead in Talcher may be due to the mining activities in and around the sampling location. Present study found the positive correlation (p<0.05) between soil, prey and feather samples of cattle egret among the eight sampling locations may be due to many of the mining, industrial and anthropogenic sources. The processes like geophagy and biomagnification may contribute to the positive correlation among the sampling habitats. Concluding this work, it might be confirmed that avian feathers can be used as non-destructive biomonitoring tool for assessment of the heavy metal contamination level in various segments of different ecosystems. Hence, based on the results of the study, the environmental management plan could be suggested and implemented for better conservation of the avian fauna.

“…We found metal in similar patterns in soil pray and feathers. The use of various pesticides and fertilizers may be the cause of metal deposition in soil, prey and feather samples of birds [17][18][19][20][21][22]. The sampling site of Chandaneswar is a coastal region of North East Odisha.…”

“…The reason for the lower concentration is likely due to lower industrial activities in these areas. In another study, reported concentration of Pb ranged from 1.15 to 2.3 ppm (Gruz et al 2019 ). There was a significant rise of Pb in the feathers of Sparrow in Hajira as compared to other two birds in present study.…”

The current study was designed to determine the concentrations of toxic metals (Ni, Pb and Cr) in feathers of birds collected from four regions of NE Pakistan. Feather samples of birds (House Crow, Common Myna and House Sparrow) were collected from different areas. Atomic absorption spectrophotometer was used to determine the concentration of metals in feathers. Analysis of the data revealed that concentrations of Pb and Cr were significantly different (p < 0.05) among bird species, whereas no difference (p > 0.05) was detected among bird species (house crow, common myna and house sparrow) for Ni. A significant difference was found for the concentration of Pb and Ni in all the four studied regions. Whereas, non-significant difference was found in all the studied regions for the concentrating of Cr. It was revealed that there is significant rising concentration of metals (Pb, Cr) in feathers of birds in Azad Kashmir.

Background: Contamination by heavy metals has been a major threat locally, regionally, and globally because it affects the structural and functional properties of an environment. The aim of the study was to assess the concentration of heavy metals (Pb, Cd, Cr, and Mn) in the feathers of bird species sampled from three areas in Kano metropolis, Nigeria. Methods: Fifteen samples of birds' feathers were collected from industrial, residential, and commercial areas using mist-nets which were randomly placed to catch passerine birds, early in the morning from 6a.m. to 8a.m. The collected samples were then digested and subjected to atomic absorption spectrophotometry to determine Pb, Cd, Cr, and Mn. Results: The highest concentrations of heavy metals in the birds' feathers were observed in site A (Sharada) followed by site B (Kurmi market) and site C (Rijiyar Lemo), however, the difference in the concentrations of heavy metals between the study areas was not statistically significant (P > 0.05). Pb had the highest concentration followed by Cd, Cr, and Mn. The highest concentrations of metals were found in the feathers of cattle egret (Pb=89 ppm, Cd=45 ppm, Mn=0.022 ppm), mallard drake (Pb=78 ppm), hen (Cd =41 ppm), duck (Cr =2.75 ppm), rooster (Mn =0.024 ppm), and guinea fowl (Cd =41 ppm), respectively. Conclusion: The birds' feathers contained various levels of heavy metals which greatly reflect the nature of the sites. Sharada industrial area (site A) recorded the highest concentrations of metals indicating slight metal contamination in the birds' feathers especially in site A.
