The Five O'Clock Shadow!!

Mathematics sings as the tune to a time that the clip clop would say to The Cops its The Beat that they walk,

I waltz to the graph as San Francisco is more than,

simple to say that The Cops are not the grid,

for every footstep has mathematics on it's mile from too!!

Challenge the circle that people at so large walk-in and comprehend the compass,

this is not a variable,

round and round and then round about to round again Swallows.

No spit would describe that as I grew-up with The Beat,

rinse and rise to the sun shining,

maze could be a great face,

yet I know that it is The Cop,

mathematics arithmetic.

Science should blush with embarrassment as the basic portion,

translate this and veal for that is the plate of humanity,

I was told if I can't say anything nice than not to say anything at all.

Thanks 

Description

The swallows and martins have an evolutionarily conservative body shape which is similar across the clade but is unlike that of other passerines.^[7] Swallows have adapted to hunting insects on the wing by developing a slender, streamlined body and long pointed wings, which allow great maneuverability and endurance, as well as frequent periods of gliding. Their body shape allows for very efficient flight; the metabolic rate of swallows in flight is 49–72% lower than equivalent passerines of the same size.^[9]

The bill of the sand martin is typical for the family, being short and wide.

Swallows have two foveae in each eye, giving them sharp lateral and frontal vision to help track prey. They also have relatively long eyes, with their length almost equaling their width. The long eyes allow for an increase in visual acuity without competing with the brain for space inside of the head. The morphology of the eye in swallows is similar to that of a raptor.^[10]
Like the unrelated swifts and nightjars, which hunt in a similar way, they have short bills, but strong jaws and a wide gape. Their body length ranges from about 10–24 cm (3.9–9.4 in) and their weight from about 10–60 g (0.35–2.12 oz). The wings are long, pointed, and have nine primary feathers. The tail has 12 feathers and may be deeply forked, somewhat indented, or square-ended.^[7] A long tail increases maneuverability,^[11][12] and may also function as a sexual adornment, since the tail is frequently longer in males.^[12] In barn swallows the tail of the male is 18% longer than those of the female, and females will select mates on the basis of tail length.^[13]
The legs are short, and their feet are adapted for perching rather than walking, as the front toes are partially joined at the base. Swallows are capable of walking and even running, but they do so with a shuffling, waddling gait.^[14] The leg muscles of the river martins (Pseudochelidon) are stronger and more robust than those of other swallows.^[7][14] The river martins have other characteristics that separate them from the other swallows. The structure of the syrinx is substantially different between the two subfamilies;^[5] and in most swallows the bill, legs and feet are dark brown or black, but in the river martins the bill is orange-red and the legs and feet are pink.^[7]
The most common hirundine plumage is glossy dark blue or green above and plain or streaked underparts, often white or rufous. Species which burrow or live in dry or mountainous areas are often matte brown above (e.g. sand martin and crag martin). The sexes show limited or no sexual dimorphism, with longer outer tail feathers in the adult male probably being the most common distinction.^[15]
The chicks hatch naked and with closed eyes.^[16] Fledged juveniles usually appear as duller versions of the adult.^[1]
