Objective: Grade: 2 Students will observe that bird beaks have different shapes and that these Subject Areas: Physical science, Life differences are based on habitat, diet Science and behavior. Skills: predicting, observing, comparing, Materials modeling tools, identifying • Assorted bird beak relationships materials (see attached list) Duration: 1 hour Standards Connections: Strands: Excellence in Environmental Education Guidelines adaptations, physical Strand 1 —Questioning and Analysis: F) Learners understand that characteristics, forces, oral relationships, patterns, and processes can be represented by models. Strand 2.2—Environmental Processes and Systems A) Organisms, instructions populations, and communities: Learners understand basic similarities and differences among a wide variety of living organisms. They understand the concept of habitat. B) Heredity and Evolution: Learners understand Vocabulary that plants and animals have different characteristics and that many adaptation of the characteristics are inherited. C) Systems and connections: Learners understand basic ways in which organisms are related to their carnivore environments and to other organisms. diverse herbivore California State Educational Standards: Physical Sciences 1d: Students know tools and machines are used to invertebrate apply pushes and pulls (forces) to make things move. omnivore Life Sciences 1c: Students know many characteristics of an organism are inherited from the parents. Some characteristics are caused or influenced prey by the environment. probe Life Sciences 1d: Students know there is variation among individuals of one kinds within a population. species Investigation and Experimentation (I and E) 4a: Make predictions based on observed patterns and not random guessing. 1 and E 4c: Compare and sort common objects according to two or more physical attributes (e.g. color, shape, texture, size, weight) Background and flattened and sometimes have heads like a hammer.

One group birds worldwide representing an patted brain so they can use their in particular, the corvids, fit into this incredible diversity in form. In the King Range National Conservation Area (NCA) there are over 300 species that frequent the area. This is due to a large degree to the diverse habitats King Range NCA found there. The different forms birds come in is closely related to their diet. However, birds don’t just use their Common Birds beaks for eating. Beaks are used for a host of other things such as nest Killdeer Pelagic Cormorant building, preening, and attacking Mourning Dove Western Gull those that are viewed as a threat. California Quail Band-tailed Pigeon Anna’s Hummingbird Acorn Woodpecker Many birds are carnivores and eat Allen’s Hummingbird Northern Flicker meat exclusively.
