For the mistletoe, this viscous goop – and by the way, viscous comes to English from viscum – is crucial. The stickiness means that, after eating the berries, birds often regurgitate the seeds and then wipe their bills on twigs – leading to the seeds' getting glued to the tree, where they can germinate and begin the cycle anew.

The larynx is the instrument of the voice, of which the rima glottidis is the immediate organ. [...] The change of the voice from acute to grave at the time of puberty, when the larynx undergoes a remarkable development, as well as its acuteness in females, whose glottis is less by one third than that of man, shew that the size of the aperture has a great influence.

The adaptation of the form of the teeth on both sides to this position, and the accurate adjustment of their contiguous surfaces, shows that it is a natural conformation.

The process of evolution of the specialised heterodont dentition of the Mammalia, or of the Theriodontia, from the simple homodont and polyphyodont dentition of the lower Reptilia would, I think, necessarily cause a reduction in number of the successional sets of teeth, due to an enlargement of one set and a consequent abstraction of growth, energy and material from the underlying sets.

The plural form syringes is a learned borrowing from Latin sȳringes.

der

This tube is named the Windpipe, Trachea, or Aspera-arteria; […] its lower extremity, or the part at which it bifurcates, is the Lower Larynx, or the Syrinx. Besides acting as a pipe to the lungs, it is also the organ of the voice, the air in passing through it causing its membranes so to vibrate, and being so acted upon by the muscles attached to it, as to give rise to the various cries and notes emitted by birds, although the palate, the tongue, and the mandibles also operate in modifying the sounds thus produced.

1839, William MacGillivray, “Practical Ornithology. Fifth Lesson.”, in A History of British Birds, Indigenous and Migratory: […], volume II (Cantatores, Songsters), London: […] [W. Burness] for Scott, Webster, and Geary, […], →OCLC, page 19:

The role of the syrinx in psittacine sound production is still under examination, and probably differs from that of songbirds. […] For species with relatively simple syringes but complex vocal behavior (such as Grey parrots), these data imply that other structures must modify syringeal output.

1999, Irene Maxine Pepperberg, “How Does a Grey Parrot Produce Human Speech Sounds?”, in The Alex Studies: Cognitive and Communicative Abilities of Grey Parrots, Cambridge, Mass.; London: Harvard University Press, published 2002, →ISBN, page 293:

The primary sound-producing organ in a bird is the syrinx and the secondary system aiding sound production consists of the larynx, mouth, tongue and laryngeal muscles. […] Birds vocalise by expelling air over the elastic membranes of the syrinx housed within the inter-clavicular sac, an air sac in the pleural cavity.

2007, Gisela Kaplan, “Emotions, Vocal Behaviour and Communication”, in Tawny Frogmouth (Australian Natural History Series), Collingwood, Melbourne, Vic.: CSIRO Publishing, →ISBN, page 121:

The organ responsible for producing sounds during song is the syrinx, located where the trachea joins the bronchi of the two lungs[…]. Four to six muscles on either side are attached to the syrinx, and sound is produced when air is expelled through it. The flow of air induces part of the syrinx wall to vibrate and generate sound, in a similar way to the operation of the human larynx.

2010, Peter Simmons, David Young, “Nerve Cells and Animal Signalling: Songs of Crickets, Electric Fish and Birds”, in Nerve Cells and Animal Behaviour, 3rd edition, Cambridge, Cambridgeshire: Cambridge University Press, →ISBN, page 247:
