Only females have been observed to carry large prey such as mallards.
“The maximum load that a peregrine can carry has never been tested empirically, but only females have been observed to carry large prey such as mallards (Parker 1979, Dekker 1980, 1987).”
From Sexual size dimorphism, prey morphology and catch success in relation to flight mechanics in the peregrine falcon: a simulation study (2019) · cites this paper as Dekker 1980
The Waterfowl section (page unavailable) says that mallards were rarely taken and only by females. It does not say that females carried mallards, so the claim about carrying them goes beyond the reported observation. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
