    al) Scientists at Fargo, ND have studied 83 species of birds for their arrival time over ten years. The study concluded that the majority of arriving earlier than they did historically. The uniqueness of this study is that they measured FAD (First arrival dates) and AGDU (Accumulated growing degree units). The accumulated growing degree units for a time of arrival deviated from past values as much as 4-5% higher or lower depending on the species. As a whole, short distance migrants have advanced arrival times and reduced AGDU as compare to long distance migration birds (Travers, S et al. 2015) Authors studied first arrival dates of 93 species of migrants in…

    resistance the substrate has, the harder and more energy required to reach the food needed. This tied back to migratory bird’s considerations and how their habitat is influenced by their migration as they aim to reduce the amount of energy expended, especially on retrieving food. This was also proven in previous literature, such as the 2007 paper written by Andrew Geering which shows that the Eastern Curlew has a preference for less resistance in the substrate. The hydrometer reading found…

    see birds flying south, also known as migration. With the help of climate change, it is messing up the birds’ migration instinct. Not helping climate change! In an article called” How Climate Drives Bird Migration” by David Tenenbaum, he talks about this issue. Tenenbaum uses data from an irruption (sudden burst of a number of animals) study based by citizen scientist (average people recording or doing things related to science) observations climate dipoles and facultative migration, how their…

    The results showed evidence supporting both hypotheses, where 27 formations supported the energetic model, 8 for the orientation model, 8 for both possibilities, and 7 for neither. In spite of the environmental conditions that affected the readings such as turbulence and wind velocity/direction, the data showed that there was little variance in positioning between individuals, which suggests that the geese attempted to maneuver into a certain position, most likely to benefit from group flight.…
