We took a common activity used to teach adaptations, the bird beak lab, and modified it to integrate mathematical concepts like bar graphs and data analysis. While this interdisciplinary lesson targets third-grade science and mathematics standards, it also shows how mathematical ...
These fascinating facts about hummingbirds highlight the incredible nature of these tiny birds and their unique adaptations, but that is just the beginning to what there is to know about them.If you would like to learn more about hummingbirds while you color, I suggest checking out these ...

Here, we describe nestling development of the Plaintive Cuckoo and its Common Tailorbird host in southwestern China. Previous studies of this system examined adaptations at the egg stage; the host has evolved dimorphic eggs that are mimicked by the cuckoo, and mismatched cuckoo eggs are frequently...
Consequently, prey adaptations that make predators attack less crucial body parts are expected to evolve. Marginal eyespots on butterfly wings have long been thought to have this deflective, but hitherto undemonstrated function. Methodology/Principal Findings: Here we report that a...
That flightless birds are descended from birds that could fly is commonly accepted among scientists. What is not completely clear, however, is why these birds lost the ability to fly. Onehypothesissuggests thatflightbecame unnecessary for ancient birds that colonizedhabitatswithout predators, because th...
