Burrows2
- Constructed nests can be burrows, or depressions, or cleared areas on the forest floor, or leaves folded around the eggs. (froglife.org)
- Burrows in sandy soils, depressions under boulders or vegetation, crevices between rocks, and man-made nests are examples of these. (fantasticwildlife.com)
Shallow5
- Preferring shallow water relatively close to the shore, loons spend most of their time in or on the water, going to land only to nest. (versicolor.ca)
- Once a location is chosen, the female will dig a shallow bowl-shaped depression with her hind feet, deposit her eggs (anywhere from 1 to 50 depending on the species), then cover the hole with soil, leaving little indication of its presence. (nhaudubon.org)
- In this paper I take a second look at these nest structures and the attendant evidence, attempting to determine if the eggs were deposited on existing soil horizons in a normal life cycle period of the parent, or if the eggs were laid on the accreting ground surface during existing Flood conditions (even if that ground was concurrently covered with a shallow layer of water). (creationresearch.org)
- The second type of nest involved enlarging existing shallow ponds. (zmescience.com)
- Another search yielded a picture of sapsucker bark scrapings that were fairly similar but a little more random in arrangement than these (the author said that the birds make shallow depressions in the bark for the sap to flow into). (riveredgenaturecenter.org)
Coarse1

- The males alone of the capelin (Mallotus villosus, one of Salmonidae), are provided with a ridge of closely-set, brush-like scales, by the aid of which two males, one on each side, hold the female, whilst she runs with great swiftness on the sandy beach, and there deposits her spawn. (sacred-texts.com)
Redds1
- Chief among fishing faux pas with the wading community is the destruction of trout nests, called redds, which serve to keep the population going. (agfc.com)
Eggs deposited2

Downstream3
- The 14- to 25-inch diameter nest is found in quiet water near the shoreline downstream from a boulder or other natural structure that deflects and slows the current. (iowadnr.gov)
- Her tail suctioned the sand and let the current deposit it just downstream. (seaturtles.org)
- Rainbow trout and cutthroats often produce some exceptional fishing on egg patterns and corn during this time because of their tendency to capitalize on brown trout eggs that become dislodged from nests and float downstream. (agfc.com)
Behaviors3

Sperm3
- Then male takes a vertical orientation and both swim around swiftly, and eggs and sperm are released, The female leaves the nest after all eggs are released. (mnhn.fr)
- The female will tip her body to deposit a few egg while the male releases a small amount of sperm, fertilizing the eggs. (ifishillinois.org)
- They'll wait there until a mate arrives, when they'll circle the nest and turn their bellies toward one another, releasing eggs and sperm into the water. (usangler.com)
Digs2
- The female salmon digs a depression in the riverbed, where she deposits her eggs. (globalseafoods.com)
- The female digs a small depression and deposits between 200 and 300 eggs, the male fertilizes them, and the female buries them. (ufl.edu)
Intruders2

Colony1
- The penguins breed in colonies, often on rocky shore islands, and each breeding pair returns to the same breeding colony and nesting site year after year. (fantasticwildlife.com)
Habits2

Diameter1
- Each nest is a small depression, roughly 2 feet in diameter, formed by the male using his caudal fin to clear the area of debris. (ifishillinois.org)
Predators2
- Islands give protection from most predators and are the preferred nesting locations. (versicolor.ca)
- When they do, the male will remain to guard them from predators like panfish, and it can take as long as two weeks for the fry to be ready to leave the nest. (usangler.com)
Shoreline1

- Many questions seem to revolve around rapidly rising Flood waters on the one hand and the apparently slow processes indicated by in situ dinosaur egg "nesting" sites. (creationresearch.org)
- These questions arise because a first look at in situ "nests" of dinosaur eggs leads to the assumption that their occurrence must represent significant periods of time without attendant wave action from the global Flood. (creationresearch.org)
- This has caused some authors to feel that the apparent time period implied by such in situ nests must have occurred either prior to the Flood or after it, and therefore they consign these strata and those above or below them to the pre- or post-Flood period. (creationresearch.org)
Leaves2
- The female leaves the nest after spawning, but may return later to the same nest or another if she has hidden egg development. (iowadnr.gov)
