Some "bird-biology" from the Tora

Some "bird-biology" from the Tora [see especially the red-marked text]

. You have seen what I did to the Egyptians, and [how] I bore you on eagles' wings, and I brought you to Me.		ד. אַתֶּם רְאִיתֶם אֲשֶׁר עָשִׂיתִי לְמִצְרָיִם וָאֶשָּׂא אֶתְכֶם עַל כַּנְפֵי נְשָׁרִים וָאָבִא אֶתְכֶם אֵלָי:
RASHI: You have seen: This is not a tradition that you have. I am not sending you this [message] with words; I am not calling witnesses to testify before you, but you [yourselves] have seen what I did to the Egyptians. They were liable to Me for many sins before they attacked you, but I did not exact retribution from them except through you. — [from Mechilta]
and [how] I bore you: Heb. וָאֶשָׂא. This is [alluding to] the day that the Israelites came to Rameses-because the Israelites were scattered throughout the land of Goshen. And in a short time, when they came to start on their journey and leave, they all gathered in Rameses (Mechilta). Onkelos, however, rendered וָאֶשָׂא as וְאַטָלִיתיַתְכוֹן, and I caused you to travel, like וָאַסִּיעַ אֶתְכֶם He [Onkelos] amended [the translation of] the passage in a way respectful to the One above.
on eagles’ wings: Like an eagle, which carries its young on its wings, for all other birds place their young between their feet since they fear another bird flying above them. The eagle, however, fears only man, lest he shoot an arrow at it, because no other bird flies above it. Therefore, it places them [its young] on its wings. It says, “Rather the arrow pierce me and not my children.” I [God] too did that: “Then the angel of God…moved, …And he came between the camp of Egypt, etc.” (Exod. 14:19, 20), and the Egyptians shot arrows and catapult stones, and the cloud absorbed them. — [from Mechilta]
