Birds come in all sorts of sizes. Some is smaller than your hand and weigh
less than 10 grams (Willow Warbler)- others are larger than a human being and weigh up to 80
kilograms (Common Ostrich)!!
By judging the size of the bird you are watching you will be able to
eliminate a lot of birds that do not fit that size. The easiest way to do this
is by comparing the bird in question to a bird that is familiar to you. For
instance we all know the relative sizes of a sparrow, dove and a hadeda.
Ask yourself the question: In
relation to any of these birds what is the approximate size of the bird that I
am looking at? If it is the size of a sparrow, you can eliminate numerous birds
that are bigger than a sparrow in so doing making the selection process a lot
easier.
The practice to compare
the sizes of birds are also used to compare birds in difficult to identify
groups such as waders, larks and pipits.Coming back to the example mentioned
elsewhere in these web pages, if you see doves on your garden lawn, compare
their sizes and you will be able to identifying them much more easily from each other.
