This book was released on 1988 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Using a new browse-monitoring technique, short-term changes in the winter foraging behaviour of yarded northern white-tailed deer (Odocoileus virginianus) were followed over 3 winters. Hypotheses about selective browsing, shifts in foraging strategy, food patch selection, diet quality, and foraging effort were derived from optimal foraging theory. Testing of associated predictions disclosed that deer expanded their diets over the course of the yarding season, showed shifts in proportional representation of browse species in their diet, and exhibited distinct but changing preferences for certain browse types. Partial preferences in diet choices occurred, but important diet items were used in nonrandom runs once adopted into the diet. Cornus stolonifera was the dominant browse species in the diet based on construction of a functional response curve, with the use of other species influenced by C. stolonifera depletion. Deer took a greater number of twigs from denser browse plots, and made more browsing visits to dense plots over the yarding season. Browsed plots tended to be higher in total twig availability and C. stolonifera availability than unbrowsed plots for the first half of the yarding season only. Diameter at point of browsing (DPB) values increased over the season for C. stolonifera and Salix. Results indicate that winter deer foraging is a dynamic process, with high diet selectivity at the beginning of the yarding season, and gradual diet generalization in the face of overall browse depletion." --

This book was released on 2017 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildlife feeding is undertaken for a variety of reasons including increasing viewing opportunities, improving body condition, preventing starvation, and facilitating hunter harvest. I investigated anti-predator and foraging behavior at bait sites, the role of competition on bait site visitation, and spatio-temporal responses to baiting. During 2013 and 2014, I used global positioning system (GPS) telemetry and camera traps to assess white-tailed deer (Odocoileus virginianus) behavior at bait sites and implications for harvest susceptibility. Camera trap data indicated that foraging behavior was influenced by social interactions and breeding chronology. Co-occurrence of mature and immature males at a bait site negatively impacted feeding rates for immature males. I used a multi-state modeling approach to determine if deer temporally partitioned their use of bait sites based on dominance status and how the resulting patterns in bait site visitation would potentially expose deer to different sources of predation risk, depending on the activity patterns of the predator. I found that subordinate (yearling males and adult females) and dominant (adult males) cohorts avoided each other temporally at the patch level. Subordinates were more likely to use bait sites during diurnal hours during the pre- and post-breeding phases of the breeding season than dominants. Bait site visitation for dominants and subordinates did not differ during nocturnal hours in any phase of the breeding season. Lastly, I used dynamic Brownian bridge movement models and camera traps to assess harvest suscpetibility. I determined that hunters were less likely to encounter a deer at a bait site than non-baited areas in their home range, regardless of sex, age class, or phase of the breeding season. Although no sex-age class selected for bait sites over other portions of their home range during legal hunting hours, adult females were more susceptible to harvest at bait sites during the pre-breeding season than the breeding or post-breeding seasons. Conversely, adult and yearling males were more likely to visit a bait site during hunting hours in the post-breeding season than the pre- or breeding seasons. Social interactions, competitive status, and reproductive behaviors are important drivers of deer behavior and harvest susceptibility at bait sites.

Available in PDF, EPUB and Kindle. Book excerpt: Easily the most common of America’s large wildlife species, white-tailed deer are often referred to as "overabundant." But when does a species cross the threshold from common to overpopulated? This question has been the focus of debate in recent years among hunters, animal rights activists, and biologists. William McShea and his colleagues explore every aspect of the issue in The Science of Overabundance. Are there really too many deer? Do efforts to control deer populations really work? What broader lessons can we learn from efforts to understand deer population dynamics? Through twenty-three chapters, the editors and contributors dismiss widely held lore and provide solid information on this perplexing problem.

Download or read book Foraging Behaviors of White tailed Deer Odocoileus Virginianus Consuming Acorns written by Jacob Smith and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Odocoileus virginianus readily consume acorns. Acorns are large (1 - 5 g), high in lipids, and dietary lipid content affects deer survival and fecundity. Deer might also ingest acorns because of a high short-term food intake. Leaves of dicotyledous plants (browse) is the forage type commonly consumed by O. virginianus and models of browse food intake reveal that larger bite sizes increase food intake. Deer consuming browse appear to have a maximum bite size and food intake of 1.2 g/bite and 9.8 g/min, respectively. My first objective was to determine whether food intake of acorns exceeded 9.8 g/min. Interestingly, limited data indicated that food intake might decline with increasing acorn (Quercus sp.) mass. I also investigated whether larger acorns reduced food intake because of increased chews per gram of ingested material (chewing investment) and lower bite rates. I measured foraging behaviors of free-ranging deer consuming Q. virginianus (Live oak) or Q. buckleyi (Texas oak) acorns in San Marcos, Texas. I set out 200 acorns in a 1-m2 area at four feeding locations and recorded the time deer spent feeding on acorns and the number of bites and chews taken. Food intake was the product of acorn mass and bite rate. Five observers collected 92 foraging observations that ranged in length from 1 to 24 minutes from September to December 2020 - 2022. Acorn mass was measured in 57 of those observations. Observation length, time of day, and observer influenced bite and chew rates, and these variables were included in subsequent analyses. The mean acorn mass of Q. virginianus was 1.5 gm (s = 0.7) and 2.8 gm (s = 1.5) for Q. buckleyi. Using linear mixed effects models I estimated a mean food intake on Q. virginianus acorns of 27.22 g/min (SE = 5.1) and 24.55 (4.9) for Q. buckleyi. Deer can ingest acorns faster than the maximum ingestion rate of browse. Analyses of mixed-effects models indicated that bite rate was higher on Q. virginianus acorns but chewing rate was higher on Q. buckleyi acorns. Food intake was also lower for Texas than Q. virginianus acorns. An inverse relationship, however, between chewing rate and food intake meant that chewing investment declined with food intake. Elevated chewing rate when deer consumed Q. buckleyi acorns appeared to reduce food intake. In addition to acorn mass, species specific characteristics of acorns such as pliability, texture, and chemical composition might impact deer ingestive behavior. Deer behavior dictating acorn ingestion is complex and requires further investigation.

Book excerpt: This report provides a detailed snapshot of our nation's passion for wildlife and nature. It serves as a road map to guide efforts to reach more Americans to provide them with opportunities to hunt, fish, and enjoy America's wildlife and wild places. Bird/wildlife watching, hunting, fishing are not just favorite pastimes, but they share revenues from sale of licenses and tags, as well as excise taxes paid by hunters, anglers, and shooters to continue to support vital wildlife and habitat conservation efforts in every state. The report outlines the details for compilation of information and surveys to different populations and provides highlights along with statistical information represented in tables from the data collected.
