Question

Noted scientist Dr. Elsa Birde described the effect of adding a mixture of dried apples and raisins to the previous feed of sunflower seeds, millet, thistle seed, and cracked corn in bird feeders in her yard. Over three years, Dr. Birde observed that the new mixture increased the number of songbirds at her feeders, especially during the months of April and May. As she has done for several years, Dr. Birde recorded, at the same time each day, the number of birds at each of her four feeders. She noted that the third year using the mixture coincided with the largest increase. There was a twenty-five percent increase in the number of songbirds over times when this mixture was not used. Dr. Birde also noted that in the third year she used a specific ratio of the ingredients, carefully measuring, which she had not done in previous years. The third year also had a warmer than normal spring, and a construction project began in a neighborhood near Dr. Birde’s. Dr. Birde is now going to produce this formula for sale and advertise to customers that they may see the same twenty-five percent increase in songbirds at their feeders.

Which might be a cause for the increase in songbirds at the feeders?

Answer 1

I would think that the primary reason for more songbirds is the addition of dried apples and raisins to the birdfeed since the increase was noted after these were added. It may be that, since the other ingredients of the feed do not have significant sugar or sweetness, that this attracted the songbirds. The biggest increase in the 3rd year is probably a combination of a warmer spring and perhaps the construction project meant that workers there were leaving food either intentionally or unintentionally that the birds could eat as well.

Answer 2

A study performed by Dr. Birdie signified that the number of songbirds in her yard enhanced because of a modified source of food.

Explanation:

A scientific claim refers to a claim, which is postulated by a scientist because of the outcome, which he or she has attained in the research that has been conducted. In the given case, it can be witnessed that Dr. Birdie experience influx of songbirds to her yard as an outcome of the dried apple and the raisin, which she has supplemented in the diet of the birds.
