The practices and behaviors employed by the black-capped chickadee displayed selective strategies towards the active foraging of food in the months prior to winter. The chickadees would collect food at a high rate, hide them, and subsequently return for additional food. The analysis demonstrated that chickadees show very little or no preference for the height of their food source, yet the specific type of seed played a major role in their foraging behaviors. The chickadees would actively scan each seed type, and in most cases select for the black oil sunflower seed. This high nutrient food source was collected in such high volumes that the feeders needed to be replenished constantly. Lastly, the chickadees also demonstrated a selective nature for the quality of the seeds, based on various applicable criteria.

[...] The r2 and slope further support this relation, and therefore suggests that the height of the chickadees food source has no apparent implications on its foraging strategies. Table 3. ANOVA analysis for the preference of chickadees with differential seed types Table 4. Regression analysis of the height of the food source and the corresponding abundance of chickadees landing F Height null Discussion: The data collected suggests various ecological implications in terms of the calculated results. The seed height experimentation did not yield any direct trends, as the chickadees did not exhibit any sort of significant preference for height (Figure 2). [...]

[...] With the prominence of food availability, and the lack of ?sensitive? predators, the chickadees may not necessarily require any height specific strategies to resist predation. These sensitive predators may simply avoid the human presence altogether, creating a sanctuary for the less sensitive residents of the environment. With these relatively low-threat lifestyles, the chickadee still demonstrated a unique strategy in terms of their selective attributes. When presented with a varied range of seed types, the chickadees would show a selective preference for the small or ?black-oil sunflower? seed. [...]

[...] In order to test for preferences in seed height, the results of the previous experiment were utilized. The analysis was performed in the same location as the previous test, with the utilization of the apparent preferred food source (small sunflower). The trials were conducted at ground level, 40cm's height, 60cm's height, 80cm's height, and at 1 meter. For each height trials were performed for a duration of 2 minutes each. The heights were randomly chosen to ensure that no artificial patterns were induced. [...]
