Newly acquired lenses, camera advice wanted

[misspedantic 11]

I own 3 Nikon/Nikkor lenses together with roll film camera.

I am considering buying a used Nikon D7000.

The lenses are ;

70-210mm 1:4-5.6D

75-300mm 1:4.5-5.6

24-50mm 1;3.3-4.5D

I have only ever used a point and shoot type camera. I would like to take pics of birds and scenery.

Any advice welcome on pros and cons of camera choice .
