As an example, the great tit, a European songbird, uses such a signal to call on nearby birds to harass a perched bird of prey, such as an owl.

The ortolan bunting is 16–17 cm (6.3–6.7 in) in length and has a wing-span of 23–29 cm (9.1–11.4 in). [9] In appearance and habits it much resembles its relative the yellowhammer, but lacks the bright colouring of that species; the ortolan's head, for instance, is greenish-grey, instead of a bright yellow. The song of the male ortolan ...
The organ is a solid, bony structure lined with a film of membranes which air passes through as the songbird calls. While the song boxes of songbirds vary in size and intricacy, this does not necessarily determine the songbird's ability to voice their song.

The typical body length of adult members of the family is between 10 and 16 cm (3.9 and 6.3 in) in length; when the monotypic genera are added, this range is from 9 to 21 cm (3.5 to 8.3 in). In weight, the family ranges from 5 to 49 g (0.18 to 1.73 oz); this contracts to 7 to 29 g (0.25 to 1.02 oz) when the three atypical genera are removed.
Letters 16 and 17 form a two-letter word ending in P. Since this has to be UP, letter 16 is a U, which can be filled into the appropriate clue answer in the list of clues. Likewise, a three-letter word starting with A could be and, any, all, or even a proper name like Ann. One might need more clue answers before daring to guess which it could be.
The solver is given a grid and a list of words. To solve the puzzle correctly, the solver must find a solution that fits all of the available words into the grid. [1] [2] [8] [9] Generally, these words are listed by number of letters, and further alphabetically. [2] [8] Many times, one word is filled in for the solver to help them begin the ...
