The Birds of the Air - Are not two sparrows sold for a penny?

Matthew 10:29 NIV
Are not two sparrows sold for a penny? Yet not one of them will fall to the ground outside your Father's care.

The above passage comes pretty much close to when Jesus said whom to fear about. But it is also about God's Caring and Love for us.

Fear God

26 “Therefore, don’t be afraid of them, since there is nothing covered that won’t be uncovered and nothing hidden that won’t be made known. 27 What I tell you in the dark, speak in the light. What you hear in a whisper,[i] proclaim on the housetops. 28 Don’t fear those who kill the body but are not able to kill the soul;rather, fear Him who is able to destroy both soul and body in hell. 29 Aren’t two sparrows sold for a penny?[j] Yet not one of them falls to the ground without your Father’s consent.[k] 30 But even the hairs of your head have all been counted. 31 So don’t be afraid therefore; you are worth more than many sparrows.


When we see that a sparrow and its worth(a penny). We also see that when Jesus said about the "Birds of the Air". and its worth...

Matthew 6:26 NIV

Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?



The Birds in fact are an amazing creature:
The Parrot which dictates the words - 

There is controversy about whether parrots are capable of using language, or merely mimic what they hear. However, some scientific studies—for example those conducted over a 30-year period by Irene Pepperberg with an African grey named Alex and other parrots, covered in stories on network television on numerous occasions^[45]—have suggested that these parrots are capable of using words meaningfully in linguistic tasks.^[46]

Some in the scientific community are skeptical of Pepperberg's findings, pointing to Alex's communications as operant conditioning.^[47] Critics point to the case of Clever Hans, a horse whose owner claimed could count, but who instead was actually understanding subtle cues from him.^[48] In another case, Nim Chimpsky, a chimpanzee was thought to be using language, but there is some debate over whether he simply imitated his teacher.^[48] Dr. Herbert Terrace, who worked with Nim Chimpsky, says he thinks Alex performed by rote rather than using language; he calls Alex's responses "a complex discriminating performance", adding that in every situation, "there is an external stimulus that guides his response."^[48] However, supporters of Alex mention that Alex was able to talk to and perform for anyone involved in the project as well as complete strangers who recorded findings unassisted and during first contact with the bird, making the arguments of rote learning and operant conditioning difficult to substantiate.^[49]

Scientists in France and the Czech Republic have also had some success in teaching African grey parrots to label items referentially using human language, albeit using a different teaching methodology to that of Pepperberg — which was found to be ineffective in the case of the particular birds within the study.

The "V" shape in Birds - 
A V formation (sometimes called a skein) is the symmetric V-shaped flight formation of flights of geese, ducks, and other migratory birds. V formations also improve the fuel efficiency of aircraft and are used on military flight missions.The V formation greatly boosts the efficiency and range of flying birds, particularly over long migratory routes.^[1] All the birds except the first fly in the upwash from the wingtip vortices of the bird ahead. The upwash assists each bird in supporting its own weight in flight, in the same way a glider can climb or maintain height indefinitely in rising air. In a V formation of 25 members, each bird can achieve a reduction of induced drag by up to 65% and as a result increase their range by 71%.^[2] The birds flying at the tips and at the front are rotated in a timely cyclical fashion to spread flight fatigue equally among the flock members. Canada geese are a common example demonstrating the V formation.

The "V", or "Vic" formation is a basic flight formation for military aircraft in many air forces.

The Vic formation is also common in ceremonial flyovers and airshow flights.

Air Mobility Command, which accounts for 20 percent of federal fuel usage, is experimenting with autopilot changes to find the best tradeoff between the reduced drag of 'vortex surfing' and the resulting 'ride qualities' of flying through another aircraft's wake.

The Migratory Birds -  When many of us think about migration, the image of geese winging their way south in their wrinkled V-shaped flocks is one that often comes to mind. The migration of geese is an example of the annual, large-scale movement of birds between their breeding (summer) homes and their nonbreeding (winter) grounds.

There is this part of the book of Jobs, where God questions about various aspects of life. Here we find in the verse - 26 where it says:

Doth the hawk fly by thy wisdom, and stretch her wings toward the south?

Job 39 King James Version (KJV)

1 Knowest thou the time when the wild goats of the rock bring forth? or canst thou mark when the hinds do calve?

2 Canst thou number the months that they fulfil? or knowest thou the time when they bring forth?

3 They bow themselves, they bring forth their young ones, they cast out their sorrows.

4 Their young ones are in good liking, they grow up with corn; they go forth, and return not unto them.

5 Who hath sent out the wild ass free? or who hath loosed the bands of the wild ass?

6 Whose house I have made the wilderness, and the barren land his dwellings.

7 He scorneth the multitude of the city, neither regardeth he the crying of the driver.

8 The range of the mountains is his pasture, and he searcheth after every green thing.

9 Will the unicorn be willing to serve thee, or abide by thy crib?

10 Canst thou bind the unicorn with his band in the furrow? or will he harrow the valleys after thee?

11 Wilt thou trust him, because his strength is great? or wilt thou leave thy labour to him?

12 Wilt thou believe him, that he will bring home thy seed, and gather it into thy barn?

13 Gavest thou the goodly wings unto the peacocks? or wings and feathers unto the ostrich?

14 Which leaveth her eggs in the earth, and warmeth them in dust,

15 And forgetteth that the foot may crush them, or that the wild beast may break them.

16 She is hardened against her young ones, as though they were not her's: her labour is in vain without fear;

17 Because God hath deprived her of wisdom, neither hath he imparted to her understanding.

18 What time she lifteth up herself on high, she scorneth the horse and his rider.

19 Hast thou given the horse strength? hast thou clothed his neck with thunder?

20 Canst thou make him afraid as a grasshopper? the glory of his nostrils is terrible.

21 He paweth in the valley, and rejoiceth in his strength: he goeth on to meet the armed men.

22 He mocketh at fear, and is not affrighted; neither turneth he back from the sword.

23 The quiver rattleth against him, the glittering spear and the shield.

24 He swalloweth the ground with fierceness and rage: neither believeth he that it is the sound of the trumpet.

25 He saith among the trumpets, Ha, ha; and he smelleth the battle afar off, the thunder of the captains, and the shouting.

26 Doth the hawk fly by thy wisdom, and stretch her wings toward the south?

27 Doth the eagle mount up at thy command, and make her nest on high?

28 She dwelleth and abideth on the rock, upon the crag of the rock, and the strong place.

29 From thence she seeketh the prey, and her eyes behold afar off.

30 Her young ones also suck up blood: and where the slain are, there is she.
