Tar sands (also called oil sands) are a mixture of sand, clay, water, and bitumen.[1] Bitumen is a thick, sticky, black oil that can form naturally in a variety of ways, usually when lighter oil is degraded by bacteria.[2] Bitumen has long been used in waterproofing materials for buildings, and is most familiar today as the binding agent in road asphalt. However, most of the bitumen produced from tar sands is refined and mixed with lighter oils to produce synthetic crude oil that can be further refined and used in much the same way as typical crude oil.[3]

Because bitumen is very thick and does not flow easily,

the eastern kingbird hunts by catching flying insects in mid-air, an approach which requires impressive and energetic acrobatic

tangare [24]

It is safe to assume that the eastern kingbird will have a type 2 functional response to an increase in prey abundance.

The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:

Type 1: An increase in consumption
Type 2: A decrease in consumption
Type 3: Decreased consumption, followed by a quick increase.

The Eastern kingbird is likely to follow a type 1 functional response to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.
