| | Silflay Hraka: Mr Answer Man Explores The Wonderful World of Bill Curvature |
 | | Though the various avocet species do display a rather striking bill curvature, to my mind the oddest bill shape belongs either to the crossbills, where the upper and lower bills end up pointing in different directions, or to New Zealand's Wrybill, where the beak curves sideways. |
 | | In the case of the avocets and flamingos, the bill shape illustrates the differing solutions each species has evolved in an attempt to feed most efficiently on a food source they have in common; the brine shrimp, or Sea Monkeys, as they are more popularly known. |
 | | Avocets have three visual feeding methods: pecking, plunging, and snatching; and six tactile feeding methods: bill pursuit, filtering, scraping, single scything (bill is held open slightly at the muddy substrate surface and moved from one side to the other), multiple scything, and dabble scything. |
