Similar to my previous source, this source discusses how a habitat can influence the pitch and temporal structure of bird vocalizations (the Acoustic Adaptation Hypothesis). This study suggests that birds adjust their vocalization in order to enhance propagation in different habitat types, as lower frequencies are more …show more content…
It also talks about how a bird may overcome these factors and the measures it may take to do so. This is extremely resourceful, as it gives extensive insight to both the behavioural aspect in the use of acoustic communication in birds, as well as the environmental effects and how birds change the acoustic signals in accordance to these interruptions. This source is reliable as it is a published article in Advances in the Study of Behaviour.

Xeno-canto is a website that shares bird sounds from all over the world. With this website, I am able to listen, download, or even record and upload sound recordings of birds. This will allow me to explore and compare different bird vocalizations and will provide me with the opportunity to do primary research for my topic. By measuring and comparing sonograms of different bird vocalizations, I’ll be able to keep a record of changes in frequency in accordance to the different birds within a species. This source is reliable as the recordings are rated from ‘A’ to ‘E’, with ‘A’ being a good quality recording, and ‘E’ being a bad quality
