The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils. Forty-three species have been recorded in Ohio.
Nocturnal migrants land in the morning and may feed for a few days before resuming their migration. These birds are referred to as passage migrants in the regions where they occur for a short period between the origin and destination. [43] Nocturnal migrants minimize depredation, avoid overheating, and can feed during the day. [1]
Geranium maculatum, an Ohio native, is a relative of the common bedding geranium (Pelargonium × hortorum). This list includes plants native and introduced to the state of Ohio, designated (N) and (I), respectively. Varieties and subspecies link to their parent species.
The ruddy shelduck is a mainly nocturnal bird. [13] It is omnivorous and feeds on grasses, the young shoots of plants, grain and water plants as well as both aquatic and terrestrial invertebrates. On land it grazes on the foliage, in the water it dabbles in the shallows, and at greater depths, it up-ends, but it does not dive. [7]
Ohio just chalked up another unusual bird sighting. On the heels of the black-bellied whistling-duck and roseate tern comes the American avocet . Here's where you might catch a glimpse of it.
Ducks eat food sources such as grasses, aquatic plants, fish, insects, small amphibians, worms, and small molluscs. Dabbling ducks feed on the surface of water or on land, or as deep as they can reach by up-ending without completely submerging. [24] Along the edge of the bill, there is a comb-like structure called a pecten. This strains the ...
Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals. Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.
Black-bellied whistling ducks ingest a wide variety of plant material (including corn, rice, millets, several types of weeds, and other grasses), [17] but also consume arthropods (such as insects and spiders), [17] aquatic invertebrates (such as snails and other molluscs) and tadpoles [17] when available. They often feed on submerged vegetation ...
