En la familia Caprimulgidae, caracterizada por especies que anidan en el suelo, la mayoría de los huevos presenta patrones crípticos, sin embargo, algunos linajes conservan huevos blancos aparentemente conspicuos. En este estudio analizamos la evolución de la coloración de los huevos en Caprimulgidae, evaluando los factores ecológicos que podrían mantener esta diversidad fenotípica y la eficacia del camuflaje frente a depredadores. Usamos métodos comparativos filogenéticos para reconstruir la historia evolutiva de la coloración del huevo y examinar su relación con el tamaño corporal y el tipo de hábitat. Además, realizamos experimentos con huevos artificiales para evaluar potenciales diferencias en tasas de depredación. Nuestros resultados mostraron una fuerte señal filogenética en la evolución de la coloración del huevo (λ = 0.955). Los huevos maculados probablemente fueron el estado ancestral en Caprimulgidae, y luego en algunos linajes se dieron con transiciones graduales hacia huevos blancos inmaculados. Encontramos que el tamaño corporal no es un buen predictor de la coloración inmaculada de los huevos, pues estos se distribuyen de manera heterogénea a lo largo de diferentes masas corporales. Sin embargo, el hábitat si parece tener un efecto pues la proporción de huevos densamente maculados aumentó en hábitats abiertos (Kruskal–Wallis, p = 0.035; prueba de Dunn con corrección de Holm, p = 0.016) y los huevos inmaculados fueron más frecuentes en hábitats densos. En los experimentos de depredación los análisis de supervivencia mostraron bajas diferencias significativas en la probabilidad y en el tiempo hasta la depredación entre tipos de coloración, hábitats o su interacción, lo que indica patrones de depredación similares entre tratamientos. Nuestros resultados sugieren que la variación en la coloración de los huevos en Caprimulgidae está condicionada por la historia evolutiva del grupo y modulada por el tipo de hábitat.Since Wallace (1889), eggshell coloration has been hypothesized to evolve as a crypsis strategy to reduce predation risk. In the ground-nesting family Caprimulgidae, most species lay cryptically patterned eggs, yet several lineages retain apparently conspicuous, immaculate white eggs, challenging this expectation. Here, we investigate the evolutionary history of eggshell coloration in Caprimulgidae, the ecological factors associated with its maintenance, and its potential effectiveness as camouflage against predators. Using phylogenetic comparative methods, we reconstructed ancestral states of eggshell coloration and tested for associations with body size and habitat type. Eggshell coloration exhibited a strong phylogenetic signal (λ = 0.955), with spotted eggs inferred as the ancestral condition and multiple, gradual transitions toward immaculate white eggs in some lineages. Body size did not predict the occurrence of immaculate eggs, which were distributed across a broad range of adult body masses. In contrast, habitat type was significantly associated with eggshell coloration: densely spotted eggs were more frequent in open habitats, whereas immaculate white eggs predominated in dense habitats (Kruskal–Wallis, p = 0.035; Dunn’s test with Holm correction, p = 0.016). In addition, we conducted artificial egg experiments to assess differences in predation rates among coloration types across habitats. These revealed few significant differences in predation probability or time to predation among egg types, habitats, or their interaction, suggesting broadly similar predation pressures across treatments. Together, these results indicate that eggshell coloration in Caprimulgidae is strongly constrained by phylogenetic history and secondarily modulated by habitat structure, rather than being solely explained by contemporary differences in predation risk.PregradoBiólogo(a)Ecología & EvoluciónUniversidad de CaldasFacultad de Ciencias Exactas y NaturalesManizales, CaldasBiologíaOcampo, DavidUniversidad de CaldasMendiwelso, Maria ElisaOrozco Herrera, Jonathan2026-01-23T15:30:45Z2026-01-23T15:30:45Z2026-01-23Trabajo de grado - Pregradohttp://purl.org/coar/resource_type/c_7a1fTextinfo:eu-repo/semantics/bachelorThesis16 páginasapplication/pdfapplication/pdfapplication/pdfapplication/pdfhttps://repositorio.ucaldas.edu.co/handle/ucaldas/26535Universidad de CaldasRepositorio Institucional Universidad de Caldasrepositorio.ucaldas.edu.cospaAlothyqi, N., Thornton, A., & Stevens, M.
