  abstract = {{H}uman-induced rapid environmental changes can disrupt habitat quality in the short term. {A} decrease in quality of habitats associated with preference for these over other available higher quality is referred as ecological trap. {I}n 2015, the {F}undao dam containing iron mining tailings, eastern {B}razil, collapsed and released about 50 million cubic meters of metal-rich mud composed by {F}e, {A}s, {C}d, {H}g, {P}b in three rivers and the adjacent continental shelf. {T}he area is a foraging site for dozens of seabird and shorebird species. {I}n this study, we used a dataset from before and after {F}undao dam collapse containing information on at-sea distribution during foraging activities (biologging), dietary aspects (stable isotopes), and trace elements concentration in feathers and blood from three seabird species known to use the area as foraging site: {P}haethon aethereus, {S}ula leucogaster, and {P}terodroma arminjoniana. {I}n general, a substantial change in foraging strategies was not detected, as seabirds remain using areas and food resources similar to those used before the dam collapse. {H}owever, concentration of non-essential elements increased (e.g., {C}d and {A}s) while essential elements decreased (e.g., {M}n and {Z}n), suggesting that the prey are contaminated by trace elements from tailings. {T}his scenario represents evidence of an ecological trap as seabirds did not change habitat use, even though it had its quality reduced by contamination. {T}he sinking-resuspension dynamics of tailings deposited on the continental shelf can temporally increase seabird exposure to contaminants, which can promote deleterious effects on populations using the region as foraging sites in medium and long terms.},
