It could have been the nest of American Crows and they left the debris on the ground. I checked the Birds of North America online site (I can't link to it because it's a subscription site, but I hope it's OK to quote from it) - Great site, well worth joining.

Apparently crows sometimes pull living twigs off trees to make their nests, and they line them with various materials including bark strips. From Birds of North America online site: "Nest Construction Both sexes build nest; no information on relative share of each sex. Although both sexes bring in nest-lining material, female does more of detailed fine-tuning of nest lining than does male (CC). Builds nest mostly between 07:00 and 11:00 (S. S. Dickey in Gross 1946); early in morning, as early as 8 min after sunrise (Reaume 1987b); likely throughout day (CC), as in Northwestern Crow (Verbeek and Butler 1999). New nest distinguishable from old one by presence of fresh, dead twigs on ground below; these twigs fall accidentally and are never retrieved (Reimann 1942). In Encino, CA, and Stillwater, OK, pulls and breaks off living twigs from trees as well as picking up twigs from ground (CC). Gathers materials from different directions around nest tree, not from nest tree itself (Reaume 1987b). Helpers in Florida (Kilham 1989), Cape Cod, MA (Chamberlain-Auger et al. 1990), and in Oklahoma (CC) participated in bringing material to the nest. With 2 adults and several helpers bringing sticks, the congestion around the nest resulted in birds having to wait for a chance to get to the nest; helpers usually left their sticks for the female to work in (Kilham 1989). Period between completion of nest and egg-laying in Florida 6Â16 d (Kilham 1989), but Emlen (1942) reported building right up to egg-laying in California. Time to complete first nests in California 13 d (range 11Â17, n = 6 nests [Emlen 1942]; 10Â14 d [CC]); 5 and 9 d in 2 nests with helpers in Florida (Kilham 1989), 10Â14 d in Oklahoma (CC). Second nests take less time to build: 9 d (Emlen 1942); 6Â8 d (Graber et al. 1987); 5Â10 d in California and Oklahoma (CC). Structure And Composition Matter Bottom and sides consist mainly of dead branches, 0.6Â3.5 cm diameter (Reimann 1942) and usually Claire

I had a dove nest in an epiphyllum plant I had hanging under a porch roof. Like your bird - dry and safe location. What I did to water was water v-e-r-y slowly, and not have the water stream hit the dirt by the nest (big pot, nest didn't cover the entire surface). I watered often enough that I didn't need to stand there too long, and I could get slightly different parts of the pot each time. 3 or 4 sets of doves hatched from that pot over 2 years! Luckily, being a succulent, it didn't need the copious watering that my fuchsias always have, but that IS how I handled the situation. Funny enough, that plant grew like nobody's business, and got huge, and bloomed vigorously during the dove 'tenancy'.

I agree. That is not 'rotting'......that is a drying of the foliage due to insufficient water or low humidity. Extremely common with many types of indoor ferns. Keep the soil evenly moist, never completely dry. And you can bump up the humidity in the immediate area by placing the pot in a tray filled with rocks or pea gravel and water just to under the base of the pot (don't let it sit directly in the water). Indoors, this will probably need to be topped up on a daily basis.

I would most likely not repot it quite yet, give it a bit of time in its new residence. These guys can be a little melodramatic. If it’s seemingly healthy and still producing new leaves, it’s okay for now. You will likely have some really solid growth in the meantime. I have made many mistakes by repotting immediately after purchasing a new plant and caused undue stress. In fact, my biggest rookie mistake was the constant itch to repot at the first sign of roots. With that said... You COULD definitely size up an inch or two when you’re ready to pot. I would pot in a loose peat based mix. (Or coco coir blend if you have any), and NOT disturb the roots, as they look fragile. I would plop that in a new pot with a 1/3 of soil and just fill the potting mixture around it and allow it to loosen on it’s on. It is not always necessary to loosen and spread the roots.. Unsure where you are in terms of humidity but I live in dry Colorado climate and use pebble trays for all my ferns and they respond very well. I have two birds nests in the shower l and they are very happy and have no crisping, which occurs easily in them. I hope this helps!
