Biography

Nick is a biodiversity scientist interested in the ecological and evolutionary forces that underlie avian diversification, both in terms of speciation and phenotypic diversity. Nick has broad interests within ornithology, including systematics and taxonomy, color and song evolution, biogeography, natural history, and conservation. While his interests are broad, all of Nick's research involves museum collections, and he is dedicated to their growth and sustainability. Nick is also engaged with teaching and outreach to educate the broader public and increase general awareness and appreciation of biodiveristy and conservation issues.

Research Focus

Avian Speciation & Phenotypic Evolution

Dr. Mason’s research focuses on avian biodiversity, speciation, and the evolution of phenotypic diversity, as well as how birds respond to anthropogenic change. He uses museum collections, field expeditions in the Andes and beyond, genomics, bioacoustics, and morphometrics to trace diversification and guide conservation.

Answers

What time of day is best for seeing hummingbirds?
Nicholas Mason

Hummingbirds are active all day, but the best time to see them is probably dawn and dusk. In hot climates, like Louisiana summers, you are less likely to see them during midday hours.

What is the best recipe for making DIY hummingbird nectar?
Nicholas Mason

The simplest recipe is 4 cups of water and 1 cup of white sugar, which are heated up to dissolve the sugar then cooled. You do not need to add red dye, in fact, that can sometimes be harmful for the hummingbirds. Same receipe as here: https://nationalzoo.si.edu/migratory-birds/hummingbird-nectar-recipe

How can people help protect hummingbirds as they migrate through Louisiana?
Nicholas Mason

Keep cats indoors as they can kill hummingbirds and other native birds. Change your hummingbird nectar out on a regular basis (every three days or so), otherwise the feeder may grow mold or bacteria that could make the hummingbirds sick.

For the Birds: A look into the collection of the LSU Museum of Natural Science

InRegister  online

2025-02-03

Here, and continued on the second floor, rows upon rows of filing cabinets hold roughly a quarter million bird specimens spanning continents and centuries. It is the third largest university-affiliated collection in the United States, surpassed only by the University of Michigan and Harvard University, says Dr. Nicholas Mason, bird curator for the museum and assistant professor of ornithology at LSU.

HEART OF LOUISIANA: LSU Museum of Natural Science

Mason is the Curator of Birds at LSU. He takes me to a research area where scientists have collected nearly a quarter-million bird specimens.

“In terms of diversity, there’s about 11,500 or so species of birds on our planet, and we have representation for about 6,500 of those. So maybe a little bit over half,” said Mason.

Dr. Nicholas Mason takes me behind the scenes to LSU’s bird research center, where nearly a quarter million bird specimens are housed. Mason is LSU’s curator of birds. “In terms of diversity,” Mason explains, “there’s about 11,500 species of birds on our planet, and we have representation for about 6,500 of those.” This means LSU’s collection includes more than half of the known bird species on Earth.

Toward a comparative framework for studies of altitudinal migration

Ecology and Evolution

2024

The study and importance of altitudinal migration has attracted increasing interest among zoologists. Altitudinal migrants are taxonomically widespread and move across altitudinal gradients as partial or complete migrants, subjecting them to a wide array of environments and ecological interactions. Here, we present a brief synthesis of recent developments in the field and suggest future directions toward a more taxonomically inclusive comparative framework for the study of altitudinal migration. Our framework centers on a working definition of altitudinal migration that hinges on its biological relevance, which is scale‐dependent and related to fitness outcomes. We discuss linguistic nuances of altitudinal movements and provide concrete steps to compare altitudinal migration phenomena across traditionally disparate study systems.

Specimen collection is essential for modern science

PLoS biology

Plumage Balances Camouflage and Thermoregulation in Horned Larks (Eremophila alpestris)

The American Naturalist

2023

Animal coloration serves many biological functions and must therefore balance potentially competing selective pressures. For example, many animals have camouflage in which coloration matches the visual background that predators scan for prey. However, different colors reflect different amounts of solar radiation and may therefore have thermoregulatory implications as well. In this study, we examined geographic variation in dorsal patterning, coloration, and solar reflectance among horned larks (Eremophila alpestris) of the western United States. We found that plumage brightness was positively associated with soil granularity, aridity, and temperature. Plumage redness—both in terms of saturation (i.e., chroma) and hue—was positively associated with soil redness and temperature, while plumage patterning was positively associated with soil granularity.
