<s>[INST] Marvin is an avid birdwatcher and has listed all the birds he's spotted in the woods behind his house. He's listed them in a big notebook. Each line of the notebook corresponds to one bird he's seen. Each line contains the following information: common bird name, scientific name, wingspan in centimeters, length in centimeters, and weight in grams. Marvin's friend, who's also a birdwatcher, has asked him to send over all the birds that fit a certain criteria. Specifically, he's looking for birds with the following characteristics:

- The bird's common name starts with "A"
- The bird's scientific name starts with "T"
- The bird's wingspan is greater than 80cm
- The bird's length is greater than 40cm
- The bird's weight is less than 2000 grams

Write a program to help Marvin filter his notebook and extract the birds that meet these criteria.

**Example Input and Output:**

Input (notebook.txt):

```
American Robin, Turdus migratorius, 40, 23, 77
American Bittern, Tantalus tantalus, 100, 60, 1500
American Oystercatcher, Haematopus palliatus, 80, 45, 550
American Avocet, Recurvirostra americana, 80, 45, 320
American Golden-Plover, Pluvialis dominica, 60, 25, 100
```

Output:

```
American Bittern, Tantalus tantalus, 100, 60, 1500
```

Note: For this example, only the American Bittern meets the specified criteria.

**Constraints:**

* Each line of the input file contains exactly 5 fields (common name, scientific name, wingspan, length, weight).
* The values of the wingspan, length, and weight are always numeric.
* The input file is named `notebook.txt`.
* The output should be written to the console.[/INST]
